ingenious product, some tweaking required. [Posted on 2005-08-24]
I am a carpenter and I had been waiting for the release of this for a year now. I really wanted the self leveling base, but it has not been released yet. The manual base is sufficient. The design is outstandingly simple and precise. The two thumbscrews and 2 vials make it the easiest device to level that I ever saw. The magnetic cubes are a brilliant idea--extremely versatile. Great battery life (2 yrs).
My experience with it is this. When I first got it, it was obviously missing a crucial plastic part which caused it to short out upon connection. I simply put a piece of tape in its place to keep the power strip from contacting the metal cube base--problem solved. I couldn't tell whethert it was broken or deformed from the factory.
I am very meticulous about checking my levels for accuracy, and I know that very few levels come out of the store which are accurate. So naturally, I did a check on my new cube and found it to be off about 3/16" over a 6' span (used my accurate 6' level to check it). Not a big problem. The way it is designed, you can take out the vials and shim up the shoulders to get the vials to read accurately (this something that Zircon probably would not encourage, but it is too easy to do). I put about 4 pcs of clear tape on the shoulder that needed a boost and it was dead on after the first try.
I told my co-worker to buy a couple so we can share parts. He bought 2 and we compared them all. His were not broken or deformed. The bases were dead on level. We noticed that my cube had a beam that got very thick (like 1/2" thick) over a distance of about 35', while one of his cubes was a very tight beam (about 1/8" thick) at the same distance. His other was somewhere in between. So I figured this is luck of the draw. Theres nothing you can do to tweak that part.
I used the device on a project I was working on which was very complex, and I found myself saying(as I do with several invaluable tools) how did I ever get along without this?
A few more points, the base and cube retails for only $5 more than just a cube, so I would always buy a new base with each additional cube I buy. That way you can pick the best one and have extras on hand.
I'm not sure why anyone would need a dot cube. For $5 more, a line cube does it all.
My co-worker also bought the jamb pole. We were both dissapointed that it did not include a clamping system (especially given the price). But it is not hard to rig up a platform with a hand spring clamp and a piece of plywood bolted to it.
All in all, an extremely versatile tool, and a great buy (versus buying a high end rotating laser). I would highly recommend it and highly recommend tweaking it right out of the box.
