I bought it for the purpose to attach it to my cordless drill for plumb, vertical drilling and it does the job. This drill had a horizontal level, but I use it more often for vertical holes. As for accuracy, I originally gave it 4 stars, but for the application and size it warrants a 5 star rating. There are new drills with a LCD level read out for both horizontal, vertical and even distance and depth, the cost much, much more than the extra, less than $10, of the three bubble levels and still only drill holes, besides my drill still works fine.

I had alot of tee fence posts to install, i use a 1"1/8 x18 bit to predrill into the earth instead of using a slide hammer on sledge which is plain crude and not easy, but my sds hammerdrill didnt have a plumb level on it, so i siliconed one these levels on my sds drill when it was plumb with the bit in a vise, so happens it worked excellent and as i was drilling i could watch to make sure i was drilling plumb for each post hole!

I used these to level my turntable. Accuracy seems good. Easy to lose though. Good thing it's a pack of 4.

These are exactly as I expected. I machined a brass housing with a threaded rod underneath and glued the bubble level into the top. The resulting part looks like an oversized thumscrew and will fit the 1/4 threaded hole on top of a video camera, allowing the camera operator to check if the camera is level no matter where it is used.

These are very handy. Better quality than what they look like in the picture and very precise and easy to use. I bought more!

Great idea. Mounted on drill and it helps maintain a straight (not angled) drilling hole.

Bonded this to telescope tripod to get it level when setting up. I've checked it with other levels I have and it is every bit as precise as they are (typical carpenters level). Very easy to see either in daylight or under red light and easy to use to achieve level. Very satisfied.

Handy as can be, checked them against a higher quality bubble level in two directions and they are actually pretty good. I know I'll find more uses for them and have used a couple that are now stuck to what they are needed for. Good for the money.

I mean I would not use them for surveying or anything but they do a solid job helping make gross adjustments better than by eye.

I bought these to level a Tripod that didn't come with one. While there is no substitute for leveling in frame, I frequently shoot from irregular surfaces and getting close with leg adjustments is a huge time saver leaving only minor tweeks to achieve good results. It is not true that these have only two positions, level or not. They are small which makes change dramatic, but it doesn't mean that when you are close you can't tell if you need to make subtle adjustments and which direction to make them in. And level is level, they don't lie. If you have another application like a Turntable they may be insufficient but my advice would be to get a bigger one. I can throw these in my camera bag and they take hardly any space at all. My only beef is that they come in a 4 Pack and all I need is the one. Hey, 6 bucks is 6 bucks- I can get 4 Bacon Cheeseburgers for that.
