You get what you pay for. They claim it's aluminum alloy, it's not. The only aluminum on this piece of plastic junk is the magnetic mount and visor. The rest is covered in plastic. I've already tested it with another $80 Irvine tech level and they don't match. I have more confidence in the Irwin as it is made entirely of aluminum alloy. If you are an amateur looking for a cheap level then you are here. If you're a pro and looking for something specific, go ahead. Just thought I'd buy this as it was cheap and I got a Revain gift card. Otherwise I would have easily spent more money at a large dealer.
