I've tried em, just didn't seem as dependable or terribly time saving to me, my patch jobs almost always hold, and though I didn't try for long enough to know for sure it did seem I had a higher failure rate with glueless. I only ever bought one package of glueless patches.

Besides, peices of patch kit often outlast other peices of patch kit. At home when patching punctured tubes from the road I often use old unfinished tubes of vulcanizing fluid & cut up tubes for patching. Takes a lil more care but they'll hold rock solid if done well.

Maybe I've just never had an American made cycling tube, but I've found that the only real factor in how well a patchjob holds up is dependent entirely on the person doing the patching. There are different grades & qualities of tubes & patches & fluid I'd guess, but application is the real tell, a half ass job and you'll be flat again shortly.

On topic, I know folks that won't patch, I see it as a waste of resources regardless of whether or not they can afford it, it's a waste of landfill.
