I sold all machines to customers, including Milwaukee, DeWalt, Bosch Professional, Festool, Makita and Güde. Hilti can only be bought directly.
I invited manufactures and my clients to get hands on these machines regularly.
Bosch Professional are indeed quality tools. What differs is the amount of torgue for each model.
If the smallest 18V shows up with 45 Nm people are inclined at first when comparing to a 18V 60 Nm tool. But there are other things to consider. If the power is sufficient for the task, the smaller tool may do more sinks.
Additionally, you can get all machines repaired at Bosch. Even 15 year old ones. Makita will simply prompt sorry, to old. You need to get a new one. Bosch maintains each item of the device as it and you can just buy the broken part as well.
I also got some very nice deals for customers which were not listed officially.
