Review: Super easy to use! Great for anyone doing Keto! - Edited for easy reading! Super easy to use! Top tips- Always do the reading test with the ketone drops you get! This tells you if your machine is working. Make sure you have enough blood, it uses less but aim for more this will STOP the error readings thus saving you having to do it again! Great for anyone doing Keto! Especially if your at a plateau this helps you pinpoint errors or secret carbs! A great buy and after research this is the machine with the cheapest strips. ( in the U.K.) You get, machine ,travel bag , booklet, batteries and ketone bottle to test the machine accuracy just put in the chip and do a test with the ketone test dropper ( to check for accurate readings ) and off you go. ( you have to do this with each new vile of strips, they come with their own micro chip) I haven’t had a issue with readings or error messages like the other people have and I’ve used 15 or more strips so far but I do make sure I have a bit of excess blood , it does take less than the usual amount needed on other machines but I never want to waste a strip! ( this kit doesn’t come with the lancet). Really helps me keep track of how I’m doing and let’s me know if I’m still in optimal Ketosis , helped no end. Good luck on your journey hopefully my review helped you! If you have any questions just ask and I’ll be glad to help if I can. *edit, now on my third set of strips and still never had an error message, touch wood I don’t! Can only assume it’s a blood amount issue , I always have excess. Super easy to use and still highly recommend it!

## Questions & Answers

**Q: My unit used to work, but now despite buying two other new tubs of strips all I get is E4.  Any ideas?**
A: Maybe you need to check the batteries. I don't know if this product has a QC (quality control) mode but we have this on our machines in hospitals. We perform QC checks to see that our machines always work. Hope this helps.

**Q: The strips for this are not available at the moment;  are there any other brands of strips that are compatible with this device?**
A: Unfortunately, due to the current circumstances things are taking slightly longer than usual. We are expecting to have stock in 3-6 weeks.

**Q: Does it come with a sim card that fits to side of monitor?**
A: Each tub of test strips (whether they be Ketone or Glucose strips) come with their own chip (but it's not a "SIM" card as they go in mobile phones right?)

**Q: Do you need the ketone chip? As I can't  find it anywhere to buy for your product. And it is not included in package.**
A: The code chip is included in the On Call Ketone Test strips. These are not included with the meter.

### ⭐⭐⭐⭐⭐ Nifty accurate little device
*by G***Y on 4 January 2020*

This product is brilliant where you want to test both your glucose and ketose in one nifty little device. Really impressed! I even had some ketone urine strips to compare the ketone readings against and this device is unsurprisingly slightly more accurate. Yes, there was a bit of reading before hand but there's also a quick guide as an alternative if you feel confident enough to get started right away. Number 3 on the lancing device is a good level which just feels like a deep scratch. It's the best thing if you don't want to fiddle between 2 different devices for glucose and ketone readings. It could only be topped by a device that wouldn't require you to change coding tabs and strips between readings for glucose readings and then for a ketone reading and would just give an immediate reading for both glucose and ketones from the one sample but, for the price of this small device, I am happy.
