Spa Ag+ Mineral Sticks for Hot Tub, Silver Ion Mineral Cartridge Last for 4 Months Treats (4PCS, Grey)

I wasn't sure about these when I ordered them as they are much less expensive than the brand name version that we had been using previously. Turns out, they work great! We hardly use any chemicals in our hot tub and these seem to keep the water crystal clear. They are easy to use and I'd recommend them for sure.

Works fine to Swedish bathtubs

Regularly order these mineral sticks. They are off brand but do the job ant a better price than other higher priced brands.

Nine month update. Water is perfect, these work as good as HS's for a whole lot less. 5 stars Four month update. Water is perfect, so far I see no difference. Will use 1 more and change raiting to 5. I didn't think it was going to fit so I kind of man handled it and the top came off, out came the contents. So the man in me went to the Wakens old one and took the top off it. First of all it was a chore to get it off versus the Billinavy. So what's inside? Let me first say I will test this before I say anything bad about it but I already blew $12:00 so lets see. Like most of you I assume gave this a try because it had the exact formula and looked the same. We dreamed maybe we found the wholesaler or something like that. If it works the same I will be the first to say in 4 months. So what did I find? The housing looks the same but it has lighter walls. It's thinner (making it easer to open) It's just lighter all around. 2nd I what I think is the important part is the silver. The Wakens bottom 25% is what I think is silver of some kind. The Billinavy has smaller chunks thru out a lot les but who knows it may me stronger. Proof will be in the water over the next few months. But I for now I'm sure that are not the same. I gave it a 4 and hope to change it to a 5. and not a 1. Stay tuned.

Works great in our hot tub and price is very good compared to store dealer.

Came with in a week.

Works great for our 4-person hot tub

I usually use the yellow oxidizer cartridges but thought I would try this brand. After refilling my hot tub and inserting the cartridge, I went to apply the decal to remind me of the next replacement due date 4 months out and found there was no decal. The instructions say there is supposed to be a decal so I checked the other 3 cartridge boxes and found none of them contain a decal. Tempted to try to return 3 of the 4 cartridges in my order.

They do exactly what they are supposed to but for a fraction of Happy Hot Tub prices

Die Bilinavy Spa Ag+ Mineralsticks sind eine tolle Ergänzung für meinen Whirlpool. Sie enthalten Silberionen, die das Wasser frisch und sauber halten, und sie halten tatsächlich für die angegebenen 4 Monate. Das Wasser fühlt sich angenehm an und der Aufwand für die Wartung des Whirlpools ist deutlich reduziert. Eine gute Investition für alle, die regelmäßig Whirlpool nutzen!

Die Kartuschen haben zwar keinen Markennamen, aber sind genauso gut und viel preiswerter. Zu empfehlen 👍und wesentlich günstiger.

Good value and compatible with original Hotspring World

Very cost effective as a replacement of OEM Hotspring's Silver Ion cartridges Works well, fits into the correct Hot tub placement Lasts 3-4 months minimum with regular use (6-8 months with occasional use) Keeps the hot tub clean and reduces the amount of chemical reliance
