Has anyone used any that actually work?

I've had mixed success with Lezyne ones. First couple, along with the included boots have been perfect. Last couple not so good. To be fair they were on the Fatty and my Roadbike so one stretched a lot and the other under high pressure.

The Park ones have been ok, I had a couple fail but that was after a good while and long after I should of replaced the tube. Also being a cheapskate I cut them down into 4 tiny patches so I can't complain if they did fail but this isn't an issue for me now as I only run Tubeless so they're just a backup for a backup!

Nope. In the distant past I remember administering a rather desperate and ultimately futile fix/bodge involving a Lezyne one and some sellotape.

I've tried several. I use the park ones (in fact have binned my lezyne set after it caused me to have to walk a considerable distance...). The park ones have held up for the life of the tube - but really i think they should only be a trailside emergency band aid until you get back home.

I still bring them with me, but they really are emergency use only IMHO.

It's for emergency use or 'back up for a back up ... tyres are set up tubeless and I have a spare tube.

Never found them to work on a tube before but they do work on the inside of a tubeless tyre for smallish slits.

I'm running with tubes and shall be bringing a spare and some patches.

T'is only a tiny glue tube that's the difference

That chalk and the sandpaper weighs a tonne. ;-)

Seriously though I carried a full puncture repair kit as a 'back up to a back up' in the summer, it's hardly bulky*/weighty.

*especially as I store my spare brake pads in mine too.

The Leeches from Halfrauds work well if it's not wet.
Never had a success with the park ones.

Uhm, it's looking like the lightest, most packable option will just be to steal Chew's

Yes. I use Slime Skabs and they work every time for me. Last week I pinch flatted my roadie-mobile and a single Skab got me home with 80psi in the tyre. I haven't used a glue patch for many years now even though I carry them as backups.

Park ones for me - carry them as a back up but never had one fail.... last life time of tube like Chews... usually on Schwalbe tubes (not sure if that may be relevant?). I am pretty sure I've used 'em on wet night too with a careful wiping of the tube.

+1 for the park tool patches.

Always keep a pack in the saddle patch

++ 1 for the Park ones here too,my lad uses them a lot and if anyone was
Going to have one fail it's him

Park patches here for me too, don't bother with them anymore since tubeless..

Found for some reason they don't stick on certain tubes, no idea why, but they're ok with Schwalbe..

Also found that over time they start to peel off & eventually leak..

They're small, light & convenient, but I prefer to use & have much more confidence in 'conventional' patches..

Another happy Park Tool patch user here (always with Schwalbe tubes)

Also consider the scenario you'll be wanting to use it.

If you normally run tubeless then, for some reason, need to use a tube then you puncture that tube, there's a good chance the tube will have tubeless sealant on it, preventing the patch from adhering well.

If I ran tubeless, my spare tube would be a slime filled one just in case I didn't get all the thorns out before outing the new tube in

Park patches are good, and highly recommend the Park tyre Boots too, fixed a massive sidewall blowout, over 10cm long, near Florence at Easter.

Yeah I can vouch for the park patches used them loads

Okay, I've got some Park ones on the way. Obviously there is the issue of them sticking to a tube with sealant on but I figure a bit of meths, followed with a quick wipe down the leg of my shorts should sort it

Thanks for all the insight

Park work fine, but I've had them melt / slide in 30+C heat and cause a slow puncture or need replacing. I'd use them to get you home and then do a proper patch when you can.
