I have many reasons to recommend this perfect laser level to everyone. 1. It is very bright even in a well lit area, much brighter than the red laser I had. I haven't tried it outdoors, but as a professional I don't recommend anyone using a class 2 laser product outdoors in bright sunlight. If you really need to do this, spend over $500 on a rotating laser that will give you a range of up to 1600 ft 2 . It offers you three 360 degree lines, one horizontal, two vertical and one cross line. which is perfect for my needs. 3. It's pretty reliable. 4. The fact that it comes with two batteries is an absolute bonus as green lasers require more power. Two batteries can keep me going all day. 5. It's very comfortable and more compact than I expected, but it did its job perfectly. base so you can use it almost anywhere. 7. This is the best laser level you will ever find for floors. 8. With 1/4 inch mounting size, I can mount it on my camera tripod for more convenient use. 9. The laser lines are really accurate. 10. I was surprised that there is also a remote control. Imagine never having to leave what you're doing mid-work and bending down to switch lines over and over again. but to control from a distance of ten feet. IMPRESSIVE! 11. Very easy to handle all its functions. 12. The pendulum system allows the instruments to self-level and also indicates the out-of-level condition to ensure your layout is accurate. Once it is off, the pendulum is fixed. 13. Its manual mode (or they call it tilt mode). ) allows locking so it can be used from any angle. These benefits keep you productive and efficient as they improve accuracy. 14. The carrying case offers excellent protection without being heavy. 15. Most importantly, GOOD price! Overall I am very happy with this purchase. It did my job twice as fast as by hand. Buy this and get ready to work smarter!
