I bought this item from Amazon thinking I was getting pressure sentive model. They sent me the ez-529 only with cord. Apparently the ez-529 with usb cord is now the new ez-528.Amazon doesnt sell the pressure sentive pen model anymore.I went through big customer service mixup with Amazon.I dont think its Amazons fault though.Go to Ezonics and do reasearch first.They seem to have two models with EZ-528 model number and you may get wrong items.I tryed calling and email ezonics with no answers.Any company thats stupid enough to name two different models the same number and same name Epen isnt worth doing business with.
