Review on Precision Alignment with Self Leveling Visibility: Three Plane Horizontal by Brett Slater

I decided to take a chance and buy a WK3CG 3D Laser based on 7 user reviews (at the time of purchase). The product is as described and was delivered on time. I first used this laser to help me install recessed lighting in my newly remodeled kitchen. I really appreciate 90 degree angles. The product is of high quality, which greatly facilitates the work and provides a professional layout. Light green lines and easy to use. You can select one, two, or all three level lines at once. The only downside is that you cannot lock the pendulum during use. You can lock the pendulum (if switched on) only for transport or in the off position. Not enough negativity to give a star. Updated (08/22/2019). As another reviewer noted, the battery doesn't charge when the device is plugged in. Also, I fully charged the battery twice before storing this device (2 to 3 weeks) and when I pulled the laser out to use, the battery was dead. So far I've used this laser to install recessed lighting in my kitchen; level the floor in the bathroom under the tiles and hang the pictures on the wall. I have 3 more bathroom flooring projects in the works and will update everyone on durability if needed. I would appreciate a response from Wakeline that the battery is not holding a charge. Update (06/30/2021) - Wokeline answered me immediately after my update on 08/22/2019 and sent me new batteries. It's been almost 2 years and this laser (and batteries) are still working! Here's a partial list of how I've used this laser: tile on floor, install kitchen and bathroom cabinets, chair rails, crown molding, recessed lights, reposition ceiling lights, hang pictures/mirrors, install built-in speakers, etc. .Now for 60 dollars. cheaper than what i originally paid would buy more if needed. I still highly recommend it.
