I am sorry I did write a wrong review on your product!! It was meant for another supplier item!! I am very happy with your supplied item! Thank you

I tried a few of the expensive ones, promising longer use, better filtration, colour changing blah blah.But, always come back go this. 0 TDs lasts longer than others and no issues with reef tank water

Reliable, long lasting and good value buying in this quantity.

Great value for money

Abnsolu-bloody-lutely perfectTDS meter reading showing 1-2 and never more than 3, depending on mains water which is most regions has a very slight variation. this is sometimes on-a-day to day basis-Wessex Water

I use this in my Marine RO unit and this reduces my TDS to 0 every time. Seems to last longer between refills as well (might just be my perception though).

I bought this to use in my whole-house water filter system. I placed the order when I had used up the last of my previous batch, so I didn't get to use it until a couple of months later. Once the filter cartridge had been refilled with this product and I turned on the tap I noticed a foul earthy/muddy taste and aroma to the water, rendering it undrinkable. I left the filter in place and used it for 24 hours in the hope that would help, but it only got worse.I appreciated I was out of time to seek a refund, but I contacted the seller to inform them of the issue and seek their advice. I had no reply or acknowledgement of my message.I do not like leaving negative feedback as I usually find sellers are serious about providing customer support, but on this occasion I cannot avoid doing so.I have seen the positive feed-back for this product dates back to 2017/18. Perhaps this is an indication of how old the current stock is and that it may be past its use-by date.If you do buy this, I suggest you test some prior to refilling your filters - a small amount soaked in water for a few minutes should give you an idea of how fresh it is. That way you won't fall foul of missing the return/refund period.
