Setup was so fast—just place it on a metal surface, turn it on, and boom, perfect alignment. The green beam is insane in brightness. Worth every cent! 💚💡 aliexpress.com

Every item came as advertised. Laser level is very user friendly. I will be using the laser level for many purposes. The green laser is much better than the red laser. The LR8 detector will extend the range and works very well. The extra rechargeable battery gives me confidence of all day use, along with the regular double AA battery conversion kit. I like the case which holds the main components. kedekey_zc0xrf · ebay.com
