I bought this set 2 years ago and the bracket (though! No longer new, but still intended usable) including sponge is still in use. only the last pen I have a few weeks ago disposed of because I did not have refills. Sure, I had in between a couple of other pins in use (that is, 4 pins, each with a refill cartridge have not two years everyday survived), but they are much more durable and more persistent than most. The holder has a good grip, so that no stylus and no cartridge is released by mistake and also the former white (now black) Sponge still manages again to wipe the board clean-ish.
I highly recommend this set thus highly recommend it and will even buy repeatedly. The fact that it is not liable on the board for me well able to absorb, because my room is used by a number and I therefore the pins wegschließe repeatedly.
So: Very strong buy recommendation, at the price you really can not go wrong ... (less than € 1.40 per pen)
