I would still confirm any hydrometer reading against a known good hydrometer.

My first Deep Six read 0.008-0.009 low right out of the box. I had bought it right when I was getting into the hobby and I foolishly trusted it. I thought my water was 1.021 but it was 1.012. At that SG I had livestock losses after no time at all. Wasn't until I had a water sample tested by someone else did I realize what was up.

The one I have now reads 0.003 low, but at least it reads CONSISTENTLY low 0.003, so anytime I take a reading I add 0.003 and I get the "true" SG.

I'm not saying don't use these. It's your risk if you don't question a reading though. The ones I have, don't go down to 1.000 so it's not even possible to at least verify a sample of freshwater and see if you can get a value of 1.000. This is why I like the glass types better since they DO go down that far. Maybe Deep Six's design has changed in the last few years -- mine are several years old.
