Got this as I was in quick need of a laser as I left my other laser at a disgruntled ex girlfriends house. Not wanting to shell big money on a name brand laser at the moment I pulled the trigger on this. I've been using it for the past week with no issues. While I don't know how accurate it is, it's accurate enough for my needs, I compared the lines to a coworkers dewalt laser and they were pretty much dead on with each other. While doing so, I noticed the dewalt seemed to be brighter, but I rotated the hueper on the tripod, and it shines brighter on one side than it does the other for some reason, no biggie, still works for my needs at almost a third of the price. Also while looking at the lasers side by side, we were commenting on how similar they were by design, and that's when my coworker took his 12v dewalt battery of and stuck it on the hueper, while it wasn't a perfect fit, it did fit and powered the laser on. Now I'm not recommending anybody doing this, but it was interesting, we were also able to fit the hueper battery onto the dewalt and it worked as well. And in comparing the dewalt and heuper lasers, the dewalt definitely does feel more robust, but you do get what you pay for, but so far the heuper is quite a fine laser and I will continue to use it as long as it lasts. It came with a nice carry bag, an adjustable height magnetic wall attachment, a charging cord and power brick, one battery and a couple other accessories. In the end my only real complaint with the hueper is that you are unable to buy extra batteries, I may not need them, but it's nice to have incase I forget to charge one I can grab the other, so I was a little disappointed by that. Their customer service did respond fast when I was trying to buy extra batteries and were nice and let me know that it has a two year warranty. (Only one year if you don't register it) overall I am mostly pleased with it, just wish I could get extra batteries.I haven't checked the accuracy of this laser yet, I'll compare it with several others when I have time.But I do like the build design, and a Dewalt 12V Max battery works perfectly on this laser.Es un excelente lacer todo es perfecto lo único que tienen que mejorar es el imán do de se pega al metal porque es muy débil necesita aserse más fuerte para que cuando estés poniendo sielos no se balla a caer el láser graciasI use this laser every day for work and I love it. Works just as well as the big name brands. Battery life is good and I love that it’s rechargeable.This laser is much brighter than my low end 2 line green Bosch laser. I was able to order an extra battery at the time of purchase for a discount, and the laser itself was also thirty dollars off. My favorite part has to be the stand. It fits on my tripod and the micro adjustments are impossible to go without once you've used them. If it breaks in the future I may go with a higher end laser from Bosch or Dewalt, but I guarantee I'll be using that laser on a Heupar stand to take advantage of the micro adjustments. I've used it for over 30 hours in the field and have no complaints at this time. A much higher quality product than I was expecting, definitely not disappointed.Using this to frame and remodel a basement, can be used for multiple tasks. Outperforms other levels that cost 3 times as much. Super bright easily visible line inside basement with direct daylight at 50ft. Very accurate, lots of features, love the carrying case. Locking self center mechanism works well. Great tool everyone should have one.This laser level seems to be very well built. The green lines are so much easier to see than the red ones. I use this almost every day for work, and I haven’t had one problem with it yet. The lithium battery pack seems to last a long time compared to the ones that use regular AA batteries. Also the hard case keeps it very well protected. You can’t go wrong choosing this laser level, it’s a steal for the price. One thing you might want to get, if you don’t have one, is a 5/8” adapter for your tripod, since it doesn’t come with oneAwesome tool comparable to the big name lasers in functionality, accuracy, and durability.
