Review on RONGPRO Magnetic Keychain Storage Premium by Tim Larsen

I'm the kind of person who has multiple DIY projects on hand all the time. I have at least half a dozen tape measures (not counting the rules and such), and I already have several tiers (not counting the free kid's sizes that come with picture frames or chalkboards). In the end I really like them. Pocket levels due to their multi-dimensionality, which is usually not part of the mini levels. In addition, the magnet may be very strong. In terms of accuracy, one review says they aren't accurate - I'm not sure what kind of poltergeist changes the rules of physics in their house, but it's almost impossible to make an inaccurate bubble level. I have a feeling you will have to work very hard for this if it is even possible. You'll probably have to mess around with mixing the oil and water in the liquid, using different dyes and optical illusions so the user can't tell the difference between the two liquids, and even then I'm not sure you'll get the bubble could bring to center if everything was not on the level. I would add the question of whether it is possible to make an inaccurate bubble level as a side question to a college chemistry or physics exam. But I was definitely too distracted. The thing is, it's accurate. And useful. And practical, and I'm glad it is.
