surprise of the size of the laser meter

I just bought this laser meter in a DIY store with the offer of 10 repayment deferred by Bosch brief just to say that it motivated me to buy it ... I just débaler it from its box in very pretty metal (which will go very well with that already purchased from Bosch for agrafaseuse) what was my surprise to discover such a small object in a great box 10 cm 3.5 cm I used to use Devices reducing the biggest in the study or office ... I worked briefly testing the I appercu it works very well and I feel that we will work well together ... By cons I have put it 4 stars because it lacks a significant thing given the smallness of the object "strap" because we may soon escape the hands .. so I'll see if there are ways to find a home Amazon ...
