An incredibly good watch at a very reasonable price
I've been trying to find the perfect watch for my needs for several years now, and after trying a couple of the more expensive ones (in the $400 - $600 range) I decided to check out a few of the watches that claim good results at lower cost. Most of the watches I tried actually were quite good, but each lacked something I wanted. This one, the Kospet T3 Ultra, has everything I need and more. Obviously it keeps accurate time--what watch doesn't these days? But all of its other features are extremely accurate. For example, the altimeter shows an elevation for my house within 1 ft of the geological survey map for my area. Its ability to continuously track my pulse, oxygen level, and stress are phenomenal. Sleep tracking is excellent. I hope the blood pressure readings are good because I have to say my cuff does report a somewhat higher level--but within reason. The battery is lasting about 3 weeks (!), but I do have to admit that I don't use some of the more battery-intense features of the watch such as phone connectivity. I had a couple of issues that caused me to contact customer service--the response and response time was excellent. For now, my search for the perfect "smart watch" is over. But I will certainly consider any new offerings this company comes up with. Update: I decided to try the phone/text connectivity facilities of the watch, and they work very well. As I mentioned in my original review, based on other watch experience, I was hesitant because of the battery drain. But after ten days of using the phone/text connectivity, the battery is still at 75%, so adding that functionality has cost very little in battery drain. I'm even happier with the watch now than I was when I wrote the original review.

Update from my previous post from 2 stars to 5 stars
The most recent update of this watch compared to its previous version Tank 2 Ultra, new cousin, the P10 watch. I also love this watch and own the Tank 2 Ultra watch, Tank3 Ultra and now the P10. I had to buy the P10 directly from the Kospet website because I bought it as soon as it was available, and it had not yet been available on Amazon. There is little difference between the Tank 2 Ultra 2 and the Tank 3 Ultra...so i focused my comparison with the previous model as i had more time to test and wear it. With that caveat mentioned, below is a breakdown of the two. Here’s a quick comparison of swimming laps and water-related use between the Kospet P10 and the Tank 2 Ultra (Tankwatch 2 Ultra/Tank3 Ultra). Note: exact specs can vary by firmware, so check your device’s latest updates. I’ve highlighted typical strengths and trade-offs. Quick comparison: Kospet P10 vs Tank 2 Ultra (swimming-focused) 1) Water resistance and swim metrics Kospet P10** Water resistance: IP68/IP68-like rating often advertised; some models also claim 5ATM. Verify your unit’s rating in the user manual. Swimming features commonly include: basic lap counting, stroke recognition, and pace/heart rate monitoring during workouts. Tank 2 Ultra** Water resistance: Generally rated 5ATM (up to 50 meters) for swimming. More mature swim tracking in many models: automatic lap counting, distance, pace, stroke type detection on many builds, and sometimes more advanced swim metrics (SWOLF, stroke rate, and endurance metrics) with robust GPS/GLONASS support for open-water swim when applicable. The bottom line is that both can handle pool swimming, but the Tank 2 Ultra typically offers more mature swim analytics and broader water-resistance status checks in practice. 2) Swim metrics and accuracy Kospet P10** Pros: Decent pool lap counting, simple stroke/pacing readouts, decent HR monitoring during laps. Cons: Stroke detection and distance accuracy can be less consistent, with occasional GPS-free measurements or drift in long sessions. Tank 2 Ultra** Pros: More refined swimming metrics (often accurate lap counting, distance, pace, SWOLF, stroke type, stroke rate). If it has GPS, open-water tracking is more reliable. Cons: Higher likelihood of needing firmware updates to optimize swim metrics. Bottom line: Tank 2 Ultra generally provides more advanced and reliable swim analytics. 3) Heart rate and health tracking during swims Kospet P10** HR sensor on wrist; works during swims if properly sealed. Sleep/activity features standard. Tank 2 Ultra** Robust HR monitoring with continuous tracking, often better stability during workouts due to more mature sensor tech and software optimization. Bottom line: Tank 2 Ultra tends to deliver steadier HR data during swims. 4) GPS and open-water swimming Kospet P10** If equipped, GPS can work for open-water workouts, but many budget models have inconsistent GPS performance and may rely more on pool mode. Tank 2 Ultra** Usually better GPS performance and open-water swim support, including route mapping and distance tracking. Bottom line: Tank 2 Ultra has an edge for open-water swimming. 5) Ecosystem and app experience Kospet P10** Kospet app ecosystem, reasonable exercise history, basic analytics, and typical third-party app integration. Tank 2 Ultra** Often pairs with more mature app ecosystems, better workout export options (FIT/GPX), and sometimes more polished coaching and analytics dashboards. Bottom line: Tank 2 Ultra generally offers a stronger data and export experience. 6) Battery life in swimming mode Kospet P10** Typically decent battery life; swimming sessions drain battery, but basic tracking is efficient. Tank 2 Ultra** Higher-end display and features can use more power; however, it’s designed to last through several workouts depending on settings (GPS on vs off, HR tracking, etc.). Bottom line: Expect similar day-to-day endurance; enable GPS only when needed to conserve battery. 7) Durability and usability in a pool Kospet P10** Lightweight, good everyday wear; ensure you have a secure strap and proper sealing for pool use. Tank 2 Ultra** Rugged design with trusted waterproofing for swimming; often has better overall build and reliability in wet conditions. Bottom line: Both are pool-friendly, with Tank 2 Ultra typically offering more rugged confidence. Recommendations based on priorities If your priority is detailed swim analytics (lap counts, SWOLF, stroke rate, open-water tracking) and robust GPS support, consider the Tank 2 Ultra as the stronger swimmer-focused option. If you want a more budget-friendly option with solid pool metrics and good battery life, the Kospet P10 is a viable choice—just expect slightly less precise swim metrics and tracking finesse. Quick tips to maximize swimming performance with either watch Ensure the device is properly tightened and wetted before swimming to improve HR accuracy. Verify you’ve enabled pool swimming mode (if available) and set pool length correctly in the app. Keep firmware updated for the latest swim metrics improvements. Calibrate stroke recognition by doing a few test laps if your model offers manual calibration. One can't go wrong with either watch, and given the frequency with which I have enabled the watches to monitor vitals, my battery life is much shorter than the typical default settings, so I end up rotating between the two to avoid potential battery exhaustion during workout times. New updated post: The customer service was excellent, and they refunded my purchase without a hassle. I will be repurchasing this watch because I love it that much! And, when you have a company that stands by their products the way this company does, I will gladly give them as well as this watch, another try. Excellent job, customer service, and company 👏 The old post was the following: I bought this watch in October 2024, and have worn it virtually every day until today, January 15th, 2025. I swim 3x to 4x per week in a local swimming pool, and this watch does a great job keeping a record of laps and my vitals. But today, the screen was blank for about 30 seconds while in the pool, then remained blank permanently. It still has a charge, and I've dried it out. I can tell the rest of the watch is working without the screen because it still vibrates, and the back of the watch that measures body info is flashing as usual. The Amazon website says a refund is only available for 30 days. They had me contact the seller, which I just did on their website. I hope they respond and make this right by repairing or giving me a discount or replacement watch. As I said, I loved this watch more so than my Garmin Swim2 watch, but it's still working, and this one isn't. I hate to think that I spent a large amount of money on a watch that didn't last 6 months.

100% recommended!
100% recommended for the price and product quality. It was a gift and the person loved it; they still use it. The screen had cracked, and I was able to easily find a replacement part.

A disappointment. The 4 buttons do not work after 4 months of use.
Bought Nov 29; today March 15, yesterday the buttons worked fine, today with 54% battery the buttons DO NOT WORK AT ALL, NONE OF THE 4; last night I left the watch on top of my bed and went to sleep, today morning I find it on the floor, obviously it falls from 2 feet height, 2 feet height, a watch with military standard quality, falls from 2 feet and the buttons (all 4) stop working... and take note just after 4 months of soft use, no, no, no. A disappointment. UPDATE: Customer service was excellent, I still give it 3 stars, because the problem is totally no sense, all four buttons suddenly stop working and with no explanation other than the military grade watch fell from 2 feet high.

Disappointed
For the money, you would expect it to last at least a year. Had an issue with connectivity early, had to delete it and redownload it under a new account. Inconvenient, but not the end of the world. Worked fine for months, then last week it froze up. Went home and put it on the charger to see if anything would happen, next morning, it came back on but only at 50% charged. Wore it a couple of days, and now, nothing, it won’t cut on. Dead screen. Very disappointing. Waiting on any reply. Not getting my hopes up.

Comfortable, Lightweight, and Looks Great
I love this watch. It’s comfortable enough to wear while sleeping, which makes sleep tracking easy. It tracks heart rate, steps, and blood pressure, although the blood pressure readings aren’t very accurate. The watch looks great, the size is just right—not too big—and it isn’t heavy at all. Overall, I would recommend this watch.
