Inferior Patch
I bought these patches on eBay thinking the backing would be easier to peel than the ones with foil. They are, however the patches are so thin that the hole they're covering blows a hole through them. I had the patch over a small hole and as I inflated the tube the hole blew through the patch. These might be suitable for lower pressure applications......but certaintly not effective for road tubes.

Get REMA or you're just playing around.
A patch shouldn't blow when it's installed in the tire.

Another vote for Rema patches and fluid. More expensive, yes, but they just work. Never have to worry if it's going to fail unless it's operator error.

I'd actually like to see a pic of the hole blown through the patch.
Just to prove this isn't a troll post.

Trust me, the patches are garbage. The one with the hole is in the garbage. You can buy them and see for yourself if you want further proof 🙂. I just felt the need to post so others would be warned.

I've had the non-glue instant patches fail after many miles, but the air leaked out BEHIND the patch. It's just harder to visualize the air forcing its way THROUGH the patch while the patch was in direct contact with the tire.

Dig it out of the garbage.
How would I know WHAT patches to buy? Not even a real link to alleged "bad" patches.
(Why would I buy more patches when I have plenty of REMA's?)
Warned about what? A picture?

Just to be clear, a hole was blown through the patch WHILE the tube was installed?

Have to admit I fell for the cheap "100 patches for $2 including shipping from China" as well as OP. They looked just like REMA patches so I thought why not. I still have some in Garage. Junk now and they were junk 2-3 yrs ago when I got them. I have no good ones and I've been trying to patch with them but unlike OP the tinfoil on my cheapies won't come off.
I'll post photos them after supper.
Update I found one on top of garbage. Sorry for quality of photo. Should be able to see that it tore when peeled as firmly stuck to tinfoil. Usually we glue tire then when glue is dry, peel off the patch and attach but not with these bastards. Even those Parks no glue tabs worked 100% better.

Sorry, I should have been more clear. Yes it would be difficult to see how a hole blew in the patch with the patch pressed against the tire. The hole blew in the patch while I was inflating the tube before putting it in the tire. I was inflating the tube to make sure there were no leaks from the patch when the patch developed a bubble in the center and grew until it burst. It was only inflated to 40 psi when it blew.
I hope this clarifies my post.

In any case. before you give up on the patches, try installing the tube in the tire, inflating to 30% more than your normal pressure and see if they hold up. If they do, then you should be good to go.

So the patch failed in an application for which it was never intended. Big deal. If anything, this proves the patches adhere well to tubes and can withstand much greater expansion than they will ever see when used properly. I'd say that's a pretty good recommendation for them being used to repair holes in inner tubes for tires. As for using them when blowing up balloons, maybe not.

I'm surprised anyone is surprised those patches are junk.

40psi while outside of the tire 🤣 I guess OP succeeded in his/her destructive test case.
Still, I do wonder whether it would have held if installed inside the tire.

I don't think you can inflate an unenclosed tube to 40 psi. Wasn't there a recent thread about this.

Let me guess, found on Amazon right? Nothing against Amazon, but to be polite, there are a lot of inferior products listed on their site. Looking on the bright side, I doubt you paid much, and free shipping!
