The experience was very straightforward. I was able to track my package the entire time with no problem. I think it came in a reasonable about of time, it came in about 10-14 days. I think that's pretty standard for a package coming out of China, but I'm not sure, this was my first time. I would definitely from them again because the PTM7950 50x31mm pad I purchased performs better than I had anticipated and I want more so I can replace the thermal paste in my graphics cards! Highly recommend using MODDIY.
