Ebay refractometer? Good or bad?

[BioCube14]

Anyone ever try one of these out? I was thinking about buying one. It seems everyone on ebay is selling the same one just slightly different prices.

If you look on ebay for a seller: dealsforyourpets, I BELIEVE (but I'm not positive) that this is the outlet for Drs Foster Smith. They seem to have a LOT of "customer returns" of this item...

i had a "cheaper" unit sold by marine depot and drfostersandsmith and i have a more expensive milwaukee unit and i can tell you with a fair amount of certainty that they were the same

I have one that I bought off ebay and it's still working for four years. I had to calibrate it twice in that time. I'm pleased.

I purchased mine on ebay and really like it.

Tried the regular hydrometer and it was a piece of junk. It was too easy for an air bubble to throw of the results.
