Precision 10x10x29mm Picture Measurement Tools with Hanging Capability Review

. I get slightly different readings from each of the 6 depending on which of the 4 faces is omitted. Using the accuracy level as a reference, I was able to determine that each had at least one edge where it read mostly correctly.

Small size makes it easy to use on small items and in tight spaces. Not exactly in every way. It is necessary to find a side that exactly matches a known flat surface and mark it for future use, otherwise it will not be flat when used for leveling. Below is a photo taken on a known flat surface. Everyone has a side that is close to the level. It remains only to find it and mark it for future use.

I bought these to apparently level things out but after a while I got confused by the readings. They give me DIFFERENT readings (different bubble positions). I'm not sure how a simple bubble level can go wrong, but it's clear they were made without any precision or I had a bad batch. Do not buy!

As others have reported, they are not very accurate. The photo is mounted on a calibrated, precisely aligned plate. They either need to have some mechanism to customize what you're going to use them for, or hope you get a good one in-game and have a way of finding out. They are cheap and the packaging is convenient, but can be disappointing if you cannot solve the quality problem.

Why buy a bubble level? Use this to make sure the plane you set is correct, but if the plane you're using isn't pointing at a really flat surface, what you're using it for will be wrong. These are great little handy devices, but unfortunately I didn't have much control over how they were made. After seeing the reviews I was skeptical, but the price was so cheap I thought I might ask them if I could use a couple of these as a handy addition to my range finder to make sure my rifle's scopes are…

All six arrived in good condition. two of them had some big air bubbles but not as big as in the photo. A few days later I took it out of the box and looked at it again. Almost all had very large air bubbles that almost completely affected the accuracy of the measurement. I didn't see any leaks anywhere, so somehow air got in, but the liquid didn't leak out.

This is a cheap level and as many posters said you need to figure out which side is which side of the level. It's not that hard to figure out, just place them on a flat table and keep turning them until the bubble is in the center. This level is small, just what I was looking for. I found a flat side, then used double sided tape and attached it to my action cam so I could visually see if I was flat and if not, adjust the shoulder mount. The level itself is easy to read. This is the default…

These stages have slight differences. I just measured one and two sides that are 0.002 inches apart which is 0.6 degrees of length so it's not an accurate tool but really is it? I found that when the bubble touches one of the lines, the plane is about 1 degree from the center of the bubble. The photos some have posted show that the deviation can be 2 degrees below level. But like others have said, every site is different. In my case, I wanted to show if the autopilot is level. I installed and…
