Very good qaulity, supposed to be the most accurate lasers on the market.
Excellent laser system. I contacted dovoh about a year ago and did a review for them for them to put on thier blog and website.
I compared it to a Klein into a Bosch laser, and I know that it is perfectly accurate. It's about twice as bright as my other green laser from Klein. Much much more crisp line than any red laser, red lasers suck don't buy one.
The carrying case that it comes in is extremely sturdy it feels like a pistol case. The accessories included are high quality, and I like the little scissor jack lifting plate for fine tune lifting. Has an adjustable clamp for clamping onto a board or countertop. It also has magnets for a fridge or whatever.
These 360 lasers are extremely useful for flooring guy because you can start the flooring literally anywhere and know that you're going to be square to the exterior walls. Its beyond useful, it's absolutely critical for starting long runs of flooring, especially with glue down vinyl or hardwoods. They have the internals wrapped with an impact resistant rubber to try and keep it protected if it falls. No other company does that. My laser was unfortunately shipped in the unlocked position, so it was bouncing around unlocked while shipping(thats bad) and is still 100% accurate. So the Rubberized internals do make a big difference. Value for the money is insane, would be a 750 to 900 dollar set up from Bosch. Easy to use.
