Amazon Customer: The larger size of it makes it nice for desktop use. One thing I wish it that it had the same key layout as the Construction Master 5 that I've used for years on the jobsite. It would be really nice if there was dedicated keys for the cm and mm. Because the Canadian Code is all in metric I use it a lot for converting mm and m to feet and inches. Otherwise it's a good addition to any office that is involved in building construction.
