I bought it for myself, I've already looked at a dozen cars, it's great for identifying painted parts, it works great in frost down to -20 (I haven't tried it colder), it uses batteries sparingly, it shows very well both re-painting and putty
Its pros:
Compact, handy, accurate, good price, works with different metals
Has cons:
if you find fault, sometimes it’s not very convenient to look at the display, but you just need to practice holding it correctlySee full review
