I used to work with Bosch 1440 and felt the difference right away . this one has incredible power, it tries to slip out of my hand, I want to put a lace on my wrist, otherwise at some point you canโt hold it and fly away somewhere (like my Bosch from the 10th floor) although Bosch had half the power . The brace is comfortable, you just hook it to the pocket of your robe and even forget that it weighs there, it doesnโt interfere with climbing onto the stepladder and when bending over, holding the chair is excellent, the weight is small and well balanced . in short, for me, so far this is the best device that I have used in 15 years of work in construction . I managed to buy for 14367 with a promotional code . today I looked at the price and did not regret that I ordered
