Becareful
Becareful I ordered a test quantity of 4 patches. Bamboo, without my approval, upgraded the quantity of my order and deducted the cost via my paypal account. Thankfully I keep my account with very low funds and only top it up when needed, still a deduction was made. I have received the product. Not tried it out yet. I am considering changing my account details in case Bamboo try to withdraw other monies for which I have not ordered, now they have my details.
