"They work well."
"Good variety of patches and good quality!"
"Easy to fit in bike bag"
"Quick shipping."
"Nice kit to have. I patch my tubes a lot. If done correctly they last for years. Patch size is on smaller side but adequate. And ones glue is open it will cure in tube in few months or so."
"Yay!!"
"What can you say it’s a patch kit."
"A great quality product that has set the standard for years."
"I prefer standard vulcanizing patch kits over glueless ones and this fits the bill well. It is priced well compared to other brands and seems to hold up well. There is usually more rubber cement than the supplied patches need. Or maybe I'm not using the right amounts. Either way, I haven't had any issues. All in all, a good product for what it is supposed to do."
"Used these before. Tried some from Wallyworld which lasted two days. Ordered these to replace. (Wally's patches had no adhesive and were not rubber.) These are easy to apply. I have tubes with two or three patches on them that are years and years old now. Thanks. Hardest part is finding the leak."
