RE:"Show Me The Money": CANTECH April 24, 2013 Currently on Amazon.com the heart Check Pen is "Currently Unavailable. We don't know when or if this item will be back in stock." That says a lot right there.
Reviews are pretty much predicatable and I laughed out loud when one reviewer listed there is no MAC compatible software for the PEN and that he emailed CardioComm about it and has yet to receive a response.
If you are going to release a product for comsumer market, you'd better have your poop together or you'll end up like...well, um...Cardiocomm.
