3M 468MP Adhesive Transfer Tape Sheets 8" x 8" (5-Pack)

2 Part Story.Part 1 --> Very disappointed with this product. I tried to use this product to stick silicone heating pads to an aluminum sheet for my 3D printer. I had no problem feeling back the white paper while sticking the adhesive to the silicone pad. I encountered difficulty when trying to peel back the brown cover paper I order to stick the silicone pad to the aluminum plate. The adhesive kept coming away from the silicone pad and stayed stuck to the brown cover paper. Out of 5 adhesive sheets, I only managed success two times. I have awarded this product one star because I feel that given how frustrating this product is to work with, the inherent failure rate with its use, the need to buy more sheets to account for failure rate, this product represents poor value for money. I will be looking into alternate adhesive products.Part 2--> I was so confused with my negative experience that I bought another set of transfer tapes - I felt bad giving a product 1 star when many other people use and say that this is a great product. The second time round, I adhered the transfer tape to the aluminium first and then pressed the silicone pad down on top of it. It worked! Very well. All pads worked and I had no wasted pads. With this approach these adhesive transfer tapes were easy to use. Perhaps I had a bad batch on the first round? Who knows. Anyway. I decided to rescore as 3/5 instead of 1/5 stars.
