waterdrop tankless ro

I was just wondering if anyone has tried or knows if the waterdrop tankless ro units are any good?

I'm guessing to get that kind of output in a 1:1 ratio, the tds reduction is not as good as a regular RO unit. I haven't seen any tests so that is just my guess.

Membrane is rated at 2,200 gallons of water. The two cartridges are rated at 550 for the sediment and 1,100 gallons for the carbon block. At $30 per cartridge filter, and $80 for a membrane, on a $500 filter system without DI capacity on it that sucker can get expensive quickly.

Carbon block is .5 micron and sediment is .8 micron according to their info page. Likely going to clog and deplete quickly, but they do a lot more prefiltering compared to the aquarium standard of 5 micron and sometimes 1 micron for the final cartridge.

I think I saw something that said a 94% rejection rate for the membrane, where BRS advertises 99% for single membrane systems. So they use tighter prefilters and a looser RO membrane to get their flow and reject numbers.
