Sold many of the vertex click, never had a return, never made a stratus though, but if it's the same mechanism it should be fine. I also sell the executive click pen from tb which is very reliable, any jams are resolved by a quarter turn on the nib and then redoing it up. It seems that the one piece click pens seem to stand a better chance of working than the two piece which do click, but only once, on their way to the bin.
