I purchased 2 of these inner tubes to replace the tube in my commuter as I ride on pretty poor roads and was tired of getting flats due to shards of glass. I was initially impressed with the thickness of the tubes. When I went to put them on those initial impressions soon faded. They were very difficult to put on. The stim was just slightly too big and was a pain to get inserted into the hole. Then once I had everything back together and started to inflate the tire blew out at about 60 psi. I remove it check the area on the rim around the blow out but there was nothing. I thought I just got a bad tube and put the second on and again I had a blow out, this time after making it to 85 psi.

These tubes are junk. Don't bother buying them.

TL;DR: Thicker rubber does not make a higher quality tube.
