M-D Building Products 92346 SmartTool Module only

I purchased this level module for my significant other who is visually impaired. With a 10X magnifying glass he was able to tell the bubble was close to the middle with a standard bubble level, but was far from accurate. It appears that the company has change the design of this level since some of these reviews have been written. There is no apparent way to attach it to anything. If you're looking for a torpedo level, this would be it. If you need a longer level, you could probably tape it to the top of another level or buy a longer one. It appears to be a quality, well-built level with many features and it is easy to use. The sound feature is loud and clear and works well for the visually impaired or anyone who has the need to level something without watching it. We would recommend this to anyone. Thanks again Amazon for coming through.

For the most part one doesn't really need 0.1 of a degreee accuracy but personally I love that I can have it. Guess I'm one of those type A types...oh well. This thing is super accurate and has some great features. Now I should tell you M-D is no longer producing the levels for this module to go in (told to me by a distributor who said he's tried everything to get them to start producing them again because of the amount of orders he gets for them) He has only a few non-magnetic M-D made levels left in stock so if you want the levels these go in, better search hard and get them while you can. That said, I do not know if this module will fit in levels made by other manufacturers.

Liked the level but for that price it should have at least came with a battery!!

This product is good for those who want to set circles manually with altitude. (You have to a computer/palm with up-to-the minute altitude/azmimuth data to do this.) In my testing when mounted to my dobsonian telescope, the angle of the object is dead-on in a 0.8-degree FOV eyepiece! (+/- 0.1 degree error!!!) Since it's water-resistant and can handle lower temperatures, this can handle observing in tough environments. This is a wonderful product not only for home-improvement products, but astronomy! Mark

No magnetic base

The unit worked well for the first two weeks but then suddenly started displaying wildly wrong values (e.g., around 17 degrees when the unit was level). In contrast to my earlier experience with it when it was working, the calibration button no longer worked to reset the zero - instead the digits just flashed to dashes momentarily. The first time this happened, I tried physically removing and then returning the battery, and that seemed to cure it. But today, it happened again, and that step no longer worked, so I'm returning it for a different model. I'm giving it two stars for working well while it worked, but reliability is important to me, and I don't want to take a chance on a second unit having the same problem in two weeks or even two years.

I do accessibility surveys for ADA compliance. The Smart tool is the tool of choice for this work. It is accurae, does what I need it to do and is small enought to carry in luggage. All good. The thing that makes it different from competing brands is the ability to re-calibrate to factory standards on site. Very important when work must be legally defensible. That is difference in price

I can highly recommend this product. It can be used as a stand alone level, or attached to other level aids eg. wheel alignment brackets via means of removing the 2 screws and backing plate to sandwich it between whatever bracket you want to use.IT also comes with a protective case. Amazon service was execellent. Item was dispatched promptly and arrived before expected date. All round great service.
