I purchased this item to replace my older tape that had a self-applied locking mechanism - this lock had snapped off internally and measuring had become difficult to achieve over the longer distances.
The tape is easily used and read and, for the most part, works as advertised.
The auto hold facility is not as positive as the applied lock type in that once the tape is extended, the return spring causes it to creep back into its shell like a shy tortoise. This movement is slow and for the most part one can work around this.
For this reason alone I can not give it full marks.
