Surprisingly powerful for its size. Ideal for assembling furniture. It allows screwing at sufficiently low speed to avoid damaging the carrier in the absence of pre-holes. The couple is still sufficient to overcome the screws until long 60-70mm. Beyond it can have a can hurt and sometimes you end manual screwdriver but it's very rare. Its size allows to sneak around or screwdriver-drill does not pass. Adapters (elbow, eccentric adapter) are not gadgets and are indispensable for difficult access (I use it all the time). Screwing bits are solid and well adapted to most standard screws. Good life of the battery. It's one year since I and the battery still holds a charge. Some imperfections to be noted, however: - Failure # 1: no serial torque setting, you must purchase the tip accessory to be able to disengage the machine dabîmer otherwise we risk the support if we live too long. - Failure 2: low light, forced to séquiper a headlamp for working in dark places. - Failure 3: non-replaceable internal battery. I wish I could change it the day she will give signs of weakness.
