What's the best resin to buy?

Not going to buy unger again gone through 25l in 8months only make 4000l of pure a month at most

This is something that I've been wandering about as my last 25l of Unger didn't last I bought a new di vessel which is now the third. So I've got one with old resin hooked to another which brings it to TDS 4 then the new resin from Daqua labelled MGB although on invoice its tulsion 115.
So with 8L vessels and a TDS from the tap at 34 churning out 800L per week I'm looking at 2 months?
It would be good to hear what people think is best for cleaning and longevity.

tulsion mb115 from pure freedom £77.50 including VAT and delivery.i use around three 25kg bags a year(DI ONLY using  around 7000-8000L a month.tap tds 30-35).

ive never had a bad batch of resin from these guys ever.

When I bought the resin I changed over from a 10" cartridge to a 7 litre di vessel but the resin would only last the same amount of time as in the cartridge, I know I'm making more water now I have changed from backpack to van mount but not that much more though.

5 litres of tulsion lasted me a year when I first got the ro

I have just changed the pre filters and the membranes on the ro and it is coming out at 14ppm at the minute before it was around 35 ppm

What DI vessels are you using. And do the vessels deteriorate with usage.
