Spirit levels are good for medium-precision work. The bases aren't milled or polished which is frustrating, the material is cast. They are more expensive than some budget accuracy levels. Let's see if the digital functionality saves enough time in the field to be worth it. Also, it's a paid app which is annoying. I don't want to have a dedicated tablet or phone to connect to them and any tech who signs it has to download and pay for it.
