Chiloskit Bullseye Bubble Level Leveler Tool, Aluminium Case Precision Round Spirit Horizontal Campers Leveling Circular level for DIYer and Industrial, Ø2.4",Accuracy 15'/2

Says it's accurate to 5/1000, I have no reason to doubt that. Seems very accurate. I got this to level projects before pouring epoxy coats. One of the keys to successful epoxy pours is to make sure your projects are stable and SUPER level. I mean NASA engineer type level. This makes it simple to do. Lay it on the project, shim until the bubble is centered and boom. Engineer quality level. Seriously, it'll help you improve your pours. Easy to use, seems durable but like any quality measuring instrument, take care not to abuse it.

I use it to level my telescope equatorial mount, which saves a lot of time in getting the polar (RA) axis spot on. All I know about accuracy is that on a dead level level surface (actually hard to find!) it agrees perfectly with my Stabila 24" level, with the bubble exactly centered. Inserting a 1/4" strip under one end of the Stabila (an angle of 0.6 deg) moves the bubble two divisions, i.e. a reading of about 0.5 deg. And the reading stays the same if I rotate the level. Good enough for me. If you want to use it to measure actual angles, not just leveling, spend more money, probably quite a lot more.

Super quality, you get what you pay for - it's a fair price too.This is a high-resolution level, I use it for critical applications, such as leveling my mantle clock, turntable, etc.It's also durable, and well-made...dare I say it, attractive in a technical-precision kind of way.Highly recommended, I have a couple (which I compared, and got identical results, pointing to high precision as well as high resolution)

I've had smaller bullseye levels and needed a new one as i was renovating a couple of gates and fences.This one has been great for the original project and I'm finding lots of additional uses for it.If you are setting fence posts in concrete, it makes the leveling a snap (as long as you have cut at least one end "true").It also make leveling stoves and even pool tables a lot easier.Big, easy to read and nicely accurate for the price.

Funnily enough you will see quite a few turntable makers selling similar products for much larger fractions of $100, and these are not nearly as informative as this level.This one is good enough to replace my former procedure of checking with two largish one dimensional levels set at right angles. And inexpensive enough to be used with any and all the decks in my world.

This level, for my purposes, is a 5 star buy. I'm not going to debate its precision, because getting a camper to absolute level is just as comfortable and useful when it's within a few degrees. If my propane appliances don't run, and I can't cook with a degree or two off kilter, I need to rethink my use of vacation time. Besides, the quality of this level is far and above those plastic ones I've encountered over and over in the big name RV stores.Non-ferrous, metal case. Plastic window. Bubble is sized the same as dead center ring.Photos show size comparison in my hand, and what I presume to be a soldered filling hole for the fluid at the factory.2 3/8" wide. 3/8" thick. (Close enough)

OK precision for general non-critical use. I purchased five and found two defects: the bottom of the aluminum cases were not flat, and the plastic bubble insert in two of the levels were mounted crooked in their case. The bubbles also varied in size.All five of the anodized aluminum cases had a high spot near the center of the back which allowed them to rock from side-to-side making readings unreliable. The defect was easily observed when a straight-edge was held against the back. The levels would spin easily and for an amazingly long time. I wrote Preamer, who said to just return them. Preamer did not respond when I asked if the replacements would suffer from the same defects.I needed these levels to work, so I used a flat granite tooling surface and sandpaper to grind off the high spots. While sanding, I gave the levels a quarter turn frequently until the bottoms were flat. After sanding, three out of the five gave good agreement when placed on a flat level surface. For the two outliers, the high side was noted by rotating the level 180 degrees and marking the consistent 'high' side. Pressure was applied to the 'high' side while to remove material on that side of the case - then the cases were sanded again with frequent rotation until they were again flat. That solved the mounting issue. See photos.
