18mm x 9mm Circular Bubble Spirit Level BY GFNT for Tripod, Phonograph, Turntable Etc. (4 pack)

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.

Exactly what they say they are. I wish they came with an adhesive but good for the price.

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.

I've been working on pool tables for many years and I always use a standard 3 foot level across the table and this is functional in most cases and of course takes time, and I came across a floor that is unlevel has heck so I'm thinking nighare.. However using the 360° 4 bubble levels, I was able to put them on all four corners in front of the pockets and boy that made it way simplest this way because it is leveling 360° and wow much quicker. and these are just cheapies.. but they do there function well..

Great for those little things when you need that extra hand to level something. I used it to hang the movie screen level.

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.

Size and cost were the biggest factors in choosing this level and it fills both needs. Nice and bright, easy to see. Pieces are very light (plastic) so I made a couple of SS bases to both give it some heft as well as protect the housing. Will try to add pictures later. FYI, I use this to level boring bars in their tool post holder.

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.
