Have the cordless screwdriver for a week and have built a fully charged battery a full nursery and an office from IKEA. This Geling with the cordless screwdriver without problems and flabby without the battery made nonstop. The torque can be wonderfully adapted to the conditions and with the correct screws BITS makes the work even really fun! The charging time when yellow / red battery indicator is approximately 2 hours.
The only thing I noticed is negative when the "right-handed" represents the screwdriver and then stores it on the left side on the ground then the switch from forward / reverse operation adjusted to the middle position. So one must always re-adjust the direction of choice.
Otherwise, I'm very happy with the value for money and would highly recommend the electric screwdriver!
