Solid level
Magnet seems fairly strong. Plastic end caps are very secure with no play. Then the best part Made in the USA.

Works like a charm...
I received this as a gift and must say I am very impressed with it. Ver functional as it can be used on its' side as well. Perfect size too. The 36" one I have is to big as well as the 30" one I have. This work perfect for me and is very nice looking as well.

Great Level
This is an excellent level. It is metal and should last allot longer than the plastic levels. The bubble glases are easy to read. It is magnetic so it can be used to level steel studs. It is aluminum so it is light weight.

It works. It's sturdy.
Accurate and does what it's suppose to do. Lightweight but feels sturdy and looks well made. Magnet along one edge, not the strongest but functions well enough. Aluminum frame, strong plastic windows, (I've dropped it already and nothing broke.) No markings for measuring.

I am THRILLED with this level
I am THRILLED with this level!! My husband has been notified, this is Mama's level so hands off! It is the perfect size and weight to do all the things I need to do ie... hanging pictures and wall art. My husband is a builder so I've had access to those big old carpenter's levels. Much too heavy and hard to read for me. I've also used torpedo levels which are good but not big enough. This level is just right..very light weight, easy to read AND has a magnetic edge. I'm a happy girl!

Level performs nicely and has additional features
Nice level with a few noteworthy features which make this a good choice. The top reading level bubble is very nice since often you are not at a viewing angle which allows convenient viewing of the bubbles. So you can be directly on top viewing down, of the level and get a clear look at the bubble. Nice. The magnetic strip which basically is a piece of magnetic tape along the bottom of the level can be useful especially for commercial framers who may be using steel studs. For a normal homeowner, I am not sure of how useful this mag tape will be. The mag tape bottom is not strong enough to hold on a nail head or screw head, but would hold on your refrigerator or washing machine when you level those type appliances during installation. What I am not so sure about is the fact that the mag tape attached to the bottom is a bit soft which in a dirty environment could attract and hold particles of junk which could affect the level being truly level. So you will have to ensure that the mag tape is clean since it can hold onto odds and ends. The other item I like is that all the bubble tubes are enclosed in a clear hard plastic container which would make this level less prone to bubble tube breakage if something is dropped on it. A nice element of design which I liked.

Perfect level!
I use this tool for leveling pool table slate. The slate is very heavy and I would like for it to be level the first time I adjust underneath. This level helps me reduce time and energy for my job. I recommend this tool for everyone.
