This is an absolutely lovely tape measure to use, particularly if you have no one to help do measurements, which is frequently the case with me.
The tape is housed in a sturdy metal outer, with a belt clip on the rear (never used that, so I don't know how good it is, but it seems strong) and is a fairly weighty beast (but not too heavy for utility). The measuring tape itself is an inch across, so it is easy to read and, if you do pull it all out, there is a warning at the end of the reel that you have got no more tape left - which has prevented me from yanking out too much tape and breaking it (although I think that would be difficult as it does feel very robustly made).
The tape is a very useful 10 metres long, which makes it an excellent all rounder for someone that only does small DIY jobs and occasional measuring for garden work. I did have the 5 metre tape and that was also a very nice tool, but I did find I had to frequently do multiple measurements (until it went missing, providing a good excuse for me to upgrade to the longer tape). One of the best features is the lock, which holds the tape firmly at the point it is applied until you choose to release it again - such an advantage when there is no one to hold the other end of the tape.
In summary, any of this range of tape measures works well, the longer the tape the heavier the unit gets and vice versa. I would recommend the 10 metre length as I have rarely needed to do multiple measurements with it and it will probably suit most requirements. There is even a white block on the item label that provides a useful area where you can add your name to the item - it might prevent your measure going the same way as my 5 metre version...
