Very good quality at a bargain price

Used in addition to a drill / driver Bosch without wire (delivered with one unfortunate tip)
Note that the tips are not going directly into the screwdriver but first must install the adapter on the screwdriver because the heads are too small to be mounted directly (even in a Bosch screwdriver)
Then just pull the ring (spring), position the head and then let go, it automatically without screwing greenhouse. Pllutôt convenient bit changes rapidly (more convenient than to squeeze in the screwdriver itself)

The +
- Seems very solid (to see long-term)
- Good range of any type of nozzle (flat, crucifix, 6 sides, solid and hollow star), it is more than complete
- 4 types of tips are double (they are the most used) so in total we have 27 different tips
- While stored in their handy little box
- Ring color indicating their type (but some colors are reused 2 times)
- Competitive price for Bosch

Les -
- Adapter to mount the end of the screwdriver not very annoying but creating a slight overhang (can be an advantage in some hard to reach places)
- Non-magnetic, damage
- Can not remove the belt clip from the box without breaking it

In short recommended for this award for intensive users of cordless screwdrivers
The only downside is that they are for non-magnetized, they would have been perfect (but for the price ....)
