I have 4 of their Pocket Operator things which I haven't taken out of the drawer for t least a couple of years. Do not regret a single cent of what I paid for them. If anything, I occasionally regret not (yet?) having drunk-ordered a few more - I'd quite like a PO-33 and a PO-35, but while sober I know I wont use them any more than I use the ones I already have.
