One thing that this laser level does and does well is the laser part. If you're using it as a guide to make a 90 degree angle, then you're going to be just fine.

However, it has some issues that need to be improved upon. The spirit level itself is slightly off in it's accuracy, so I wouldn't use it for that.

A more major issue for me, however, is the back battery panel, which is almost impossible to put back on when there are batteries inside. Overall, the quality of this device isn't great, but function wise when it comes to the lasers I can't fault it.

Everywhere else, it needs work.
