Now that Ive found and enjoyable compliment of tubes for my ZP3, I'm liquidating the additional tubes I bought... I can't be tempted to continue rolling.
All tubes were bought with the description of testing strong... however, I don't have a tester. If you find the tubes don't meet expectations, I'll gladly refund.
