Perfect Pi Diameter Circumference Auto-Brake Tape Measure and Layout Pocket Rule DAL120-1/2-Inch by 12ft / 3.5m

If you need to find the diameter of a tree, without cutting it down, this is the product for you. It is a tape measure that has the diameter markings with the circumference. Wrap the tape around the tree and you can read both the diameter and the circumference. The manufacturing quality is good. The tape retraction is very strong. The tape is metal. I expect that it will last a long time, as long as I don't loose it.

It works as described. Using it to measure trees. Would be good to have a way to hook or fasten the end when measuring large trees.

Compact, easy for everyday carry.

The locking mechanism does not work well. When I pull the tape out, it states locked only occasionally.The tape is compact and is very legible. I particularly like it having inches and cm on both sides - one side has the normal marking and the reverse has that to measure diameter.

recently I needed to measure something round so I bought one. liked it so much got my 3 grandkids each one. works good. well packed and shipped promptly.

This is the second Perfect Pi tape measure I have bought. Love them and recommend them to friends.

Excellent product

The auto stop which allows the tape to stay pulled out and not retract is not great but does work. That feature is why I bought this product. Numbers are large and very easy to read.
