5.0 out of 5 stars Did what I wanted it to do
Reviewed in the United States on July 15, 2024
This is my first laser level, so take my opinion for what it's worth.

This did what I needed it to do - assist in installing a shower. I didn't have much luck with the included base, (not sure what it's supposed to clamp on to!) but I was able to use my own tripods of various sizes to get the lines I needed. It does need to be dialed in level so it doesn't blink, but I would guess that's the same with every laser level. The red laser worked fine for me indoors. Never tried it outdoors.

I bought this laser level for a couple things, installing patio blocks and doing diy alignment on vehicles. Worked great for both.

This little level was a life saver when installing our kitchen backsplash. But it doesn't work well at a distance; it needs to be fairly close. I also couldn't figure out how to use it to get consistent angles, like if you wanted to do a herringbone pattern. But overall, it can be very handy!

Used to hang a privacy curtain using ceiling mounts, great to stay on line after finding your measurements. Made the install very quick and used in the time, laser was still very visible.

5.0 out of 5 stars Impressive Tool!
Reviewed in the United States on August 12, 2023
This has become one of my favorite tools at home.

The lasers are bright.

The fact that you can work on two different axis at the same time is so helpful and convenient.

But the best part of this laser is the self-leveling feature. Nobody where you put it, the devise will level itself ensuring that those laters are always straight. Gotta love technology!

Bought it during one of the Amazon Prime deals at a huge discount. Still, even at the regular price it is totally worth it.

Also, the clamp is a great feature as it allows you to mount the laser pretty much anywhere.

Once you use one of these laser levels you will NEVER go back at using regular levels.

3.0 out of 5 stars Great level except you can't see the lines outside during the day even on a very overcast day
Reviewed in the United States on May 6, 2024
Takes 2 AAs, light weight, seems rugged enough, it turns to face the wall mount which protects the screen when not in-use so you can put it in a tool box. It self levels.

It's stated to be an indoor/outdoor level up to 50 feet. So I bought this to use for an outdoor deck project but the red cross hairs weren't visible at 8 feet and it was very overcast that day. I had others check and give their opinion and they had the same conclusion.

5.0 out of 5 stars Should've gotten it years ago
Reviewed in the United States on May 4, 2021
I've been seeing videos of home remodels swearing by laser levelers for years. I didn't buy one because I had a bad experience with a laser level in the past, the ones that spin and require constant checking. If I had just bought one I would've saved myself hours of checking and rechecking. Could've used it for tile, framing, picture hanging, you name it. So my only regret is not getting it sooner.
With regard to the reviews saying you can't tilt it, I'm not sure what's going on but I was able to tilt it with no problem (see picture). The main thing is you need to make sure it's perfectly still. Otherwise it will not display. Also, the instructions say it will flash, letting you know that it's not level. It flashes off for one second, on for 3 seconds. Not exactly a "lock" function as some have interpreted, but definitely usable for angled projects if you are okay with the flashing.
Bottom line is this tool will make your life easier. Just get one.
