Review on 📊 53315 Test, Measure & Inspect for Increased Efficiency by David Stewart

Lightweight and well designed. The only complaint I have about the device is that the bottom edge of the device feels a bit rough. As other reviewers have said, it looks like it broke out of shape. However, a quick registration solved this problem. The overall flatness of the two built-in levels is close enough to my portable level that it's not noticeable (especially since it's cut with a drywall saw). For reference I used Arlington LV1-10 and Arlington LV2-5 low voltage blocks (I also bought them from Revain). It is important to note that the product image shows padding in 3 corners which was not present in my version. Check out my pictures for more details. My overall rating is 4.5 stars, rounded up to 5.0 to 0.5 stars due to minor discrepancies with my level and a rough bottom end.
