I used them perhaps twice to practice tap and then I stored them in a corner of my living room (household temperature, dry California humidity). To my dismay, within a few months of 2020, they became unglued. See the photo attached. Not a single once remains useable. I explained to the company that I had been hospitalized and ill with coronavirus between March - July and didn't have the energy to investigate whether they were warranties. When I wrote them, they said to contact Revain, but of course Revain told me that the return window was only 2 weeks. WHAT A CORRUPT COMPANY SELLING A DEFECTIVE PRODUCT. I've lost my money. I reckon the only thing I can do is to warn you not to lose yours.
