While the device itself is fine, one of the reasons I bought it is the case. The case is fine, but the latch that keeps the case closed is a Rubik's Cube type POS.

I still think it's a good device but if you're going to pay more for a case don't as it's very cheap and ridiculously bad design.

This is a good instrument at best. As other reviewers have pointed out, you'll need to calibrate this item every time you use it (which is usually a chore). For example, if you choose to pre-cook, you need to calibrate it. You also need to recalibrate it to get the OG after cooking (yes, you need to recalibrate it twice if you test the OG both before and after cooking). Aside from the hassle of calibrating each time, this item seems relatively accurate (within 0.001) to my hydrometer readings.

The adjustable eyepiece for focusing is a nice feature. I compared this to other brands and it was the best
