esv bionic doser unit, good or bad?

[clownfool]

I use bionic 2 part for dosing. I like dosing with the 2 part because it's easy and works well for ME. I do get tired of dosing all the time and found the ESV dosing unit. Do any of you use this doser?
I was just wanting to know if any of yall use it and like it. I don't want to spend that much money and it turn out to be a piece of crap.

i just ordered the dual version of that one. although they only have a 30 day warrenty the guy said if any of the pumps break they are easy to replace and are cheap also like 12.00 so I thought about giving it a try.

the main thing I am worried about is how accurate they will stay but time will tell.

I've used ESVs doser in the past. On the positive side it does what it's supposed to with no problems, and the only part that can potentially fail is the air pump you use to drive it. On the negative side it's ridiculously priced for what it is (to be fair, I'm pretty sure someone is hand assembling these).

I've used an Aqua-metic for years.....I like the looks of the bubble magnus though.
