Great plumb bob
I work as a Union Commercial Carpenter and we hang doors all the time and need to make sure they are plumb. When the Tajima plumb bob came on the market they were all the rage. Moonwell took that design and in my opinion made it better and less expensive (about $10 less). Mine is in my tool box on every job. Other carpenters have borrowed it and love it too. The bob is incredibly heavy which makes it very steady for taking quick measurements so we can hang the dry wall and secure the door in place and move on. Also, the string is super long so it is useful for any job.

Works well and pretty good value
I cannot compare to Tajima brand, as I don't have a Tajima to compare to. But the Moonwell plumb bob works well and steadys really fast. Magnet holds well to metal parts and pin holds well in wood parts. Can adjust tension on the self retracting string if one would want to change the plumb to a heavier or lighter model; I haven't changed the plumb myself but I did adjust the tensioning to test.As stated before, I don't have a Tajima to compare, but seems the Moonwell offers about $8 to $10 value feature to feature on comparable Tajima model.

Works great!
Good quality and works great but if you use it enough you might pull the set nail out or bend it. Great tool for setting tall wall forms or doors!

Works great. Strong magnet
Very well worth the price. The magnet is strong, the strong works great . The mechanism that controls and retracts the strong feed works great

2 ways to mount, plenty of string, heavy Bob
I see people often comparing these to lasers. This is much cheaper than a laser, and more useful in some cases. This will allow you to measure how far away something is from a wall in comparison to something else. For that use and for vertical reference, I really like this unit. It made my garage door trim rebuild easier.The 2 mounting methods are nice. The magnet is pretty strong. The Bob is hefty and works as advertised.

Bob?
I do not know who bob is but this thing works. A magnet that sticks and string that swings until its tired and has no energy, then just hangs there.

Nice to have the extra long line and heavy plumb Bob
Works great but the spot marked on it say 2 inch but it's like 1 13/16" so that needs to be fixed, I install elevators and this is perfect for plumbing rails, and a great price

Worth it
Only issue I have with it is the body case doesn't feel as heavy duty as the Tajima.Price is niceLonger string than TajimaWorks exactly the same as Tajima
