I am referring to the Smart Sympodiums - desktop units. Not the Smartboards. These pens are wired in and touch sensitive. The screen and pen combo are extremely responsive so there is no need for these pens to break. there is very little pressure applied. Bad product.
We have the same problem and I have complained to our rep who has complained to the company. No response. The pens break in half, and the tips break off. It seems to be happening more frequently and they are expensive to replace!
