The delivery was not fast, but it arrived within the announced date.
In conclusion, it is suitable for amateur use, but it lacks performance for professional use!!
It's very simple to use. When you turn it on, the machine will automatically adjust the level, and the horizontal vertical will be displayed when you select the desired option. If you install it in a place with a lot of tilt, the alarm will sound and the work will not progress, so you can flatten it a little bit and let it work.
There are 3 laser options, weak thickness, thick thickness, and flickering laser, but after a day of using it, the laser light has become a little weaker, so I can't see it well during the day. It seems too much for professional use.
To sum up,
The advantages are that it is easy to use and cheaper than the professional one, and the accuracy is high because it automatically levels the device
The downside is the short battery life. I just bought it and used it, but the laser light weakens. The quality of the products and accessories is santi.
Please refer to it and buy it~
