4PCS Grey Mineral Sticks

Got these for our hot tub. Great product at a great price. Half the price of same product at a spa place

Helps reduce the amount of chemicals needed in the hot tub. It fits into the "floater" so use it instead of adding bromine tabs. The hot tub is cleaned often but it helps to keep the water clean in between and its effectiveness seems to last approximately 3 months. For some reason it is not available in Canada.

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.

I bought these as an alternative to the name brand, and was not disappointed in their performance. I used it for 4 months and my spa water looked as good or better than with the brand name. I'm using the 2nd one now and if this one works as well, I'll be buying again. I liked that it said silver ion as some don't. Looked just like the brand, and fit the same way.

Do not risk your Spa! These fall apart and can dump beads into Pump. They are not at all securely snapped togeather. Im returning the fallen apart pieces

So easy to use...

Great value

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.

They do exactly what it says on the box

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
