On the surface, Park Tool patch kits are incredibly overpriced for what you're buying. You're getting 6 self adhesive patches, a small square of sandpaper, and a plastic container to store them. However, they're so reliable when installed correctly, in the end, they're worth overpaying for.Every rider, whether you're carrying one inner tube or as many as three, should have a patch kit in their saddle bag, no matter what, period. There are numerous choices for patch kits, from self adhesive kits like this to patches that come with adhesive glue. With those numerous choices, you also have many, many brands to choose from. While most patch kits will work fine, I personally feel Park Tool sells the most reliable kits and I feel this kit, specifically, is the easiest to deal with on the road( Though I also use these kits to patch tubes in bulk that I've flatted with in the past).So, what can patches like this handle? This specific patch is best for road tires from 23mm-32mm or so and most holes coming from small nails, shards, and some pinch flat(though they won't take care of pinch flats that end up splitting length wise). In short, think smaller puncture types of flats and not larger length of width wise type wider flats.In terms of installation, nothing is fool proof, but I've used these to patch dozens of holes over the years, on my bikes and those I've ridden with. In that time, I've had 2 fail and they didn't fail right away but several rides later. Going further, those two failures were both due to being changed in absolutely horrible conditions where I likely didn't sand the inner tube enough and press the patch in place long enough before installing and inflating. So, I'm not saying any of the critical reviews on here are wrong, or that these can't fail, but I am saying it's my experience that it's incredibly rare, especially if you take the time to do it right.Speaking of that, this is my approach to installing these:1. After locating the hole make sure you sand around the hole in a large enough area to mimic how large the patch is. Also, it's very important that you actually sand some material away and rough up the area. I'm not saying to sand away half the tube, but I've seen far too many people barely touch their tubes with sandpaper and that just won't work. You need to sand enough to where the surface actually looks roughed up a bit and you see just the slightest amount of dusty material from the tube.2. If you have space in your bag, take some mini alcohol pads with you and hit the surface of the tube with the alcohol pad and let dry. If you don't have those available, just blow off the dust from sanding and make absolute sure the surface is dry.3. make sure the area of the flat and immediately around it is completely flat and install the patch. Make sure you get any air bubbles out and that the patch is even and fully seated. At that point DO NOT install the inner tube right away but instead, hold the area you patched between your fingers for a few minutes and allow the patch to really adhere to the tube.4. After allowing the patch to settle for a moment, DO NOT place any air in the tube outside of the tire. Instead, fully install the tube back in your tire seat the tire, THEN inflate. If you add any air outside of the tire you may prematurely weaken the bond that is still adhering. I know most people only blow just a bit of air in with their mouths, but don't even do that.If you follow those four steps, I feel extremely confident in saying that you're on the road repair will not only last you that day, but you'll get at the very least, several hundred miles out of that tube as long as you of course don't flat again. I, personally, have ridden as long as 3,500 miles on an inner tube with this patch and when it finally did fail, it was a due to a huge part of a road that was missing that I couldn't avoid, thus causing a massive hole in the inner tube.In short, these patches can and are very reliable and a very nice insurance policy that every rider should always have in their saddle bag!

These works great! They are like super glue on a sticker and stays flexible. I use them on pool floats, bike tubes. I even cut them into thirds and used them on cuts on my arm like strerie strips. If you use them on skin, they WILL NOT come off like a band-aid. They are permanent until the skin decides to let them go. But, they did stop the bleeding.

So I used 4 of the patches so far. I cleaned the inner tubes while trying to identify the exact leak location. After scuffing the areas I recleaned with 70% alcohol on a bit of paper towel which I used to wipe the area clean and dry as well right after the corner with the rubbing alcohol. I applied the patches to inner tubes with whatever remaining bit of air happened to be in them.3 of the 4 patches (yellow circle you can see 2 of the 3) adhered so well it's difficult to spot the location by site or touch.The red circle is my only reason for knocking off a star. It still covers the critical area in question but when I re-inflated both inner tubes only this single patch changed a little around the outter edges. It left a slightly sticky residue around the edge where the patch ....I'm not sure how to describe. It appears as though the glue and possibly a thinner layer may remain and the thicker bit is what didn't fully stretch with inflation. I have left out for 3 days checking if it is leaking and so far no issues and no further edge disturbance. I was concerned since my tube had a pinched wear line with a random hole hidden in what looks like a cat scratch shape. So I fit the patch originally to cover the entire scratch mark diagonally barely encompassing the scratch. It appears to still cover the entire scratch which is why I didn't say the patch let go at the edges but I can understand exactly why it looks like a failure to others. I plan to coat the sticky residue in some baby powder to keep it from trying to stick to the outter tire.Definitely a very quick handy repair patch for road side considering in seconds I had 4 patches finished and rubbed firmly into place. I've used glue kits before and I remember a lot more time waiting to dry, testing and sometimes having to reglue those so I would much rather rely on these

I love these things so much. The package is tiny, about the size of 3 or 4 quarters stacked on each other. Sticker type patches like these are less reliable than properly used glue/vulcanizing patches, but I rarely have issues with them. Most people don't use the glue-type properly, making these more reliable for the average user, not to mention much, much faster. I've had many of these patches last for years, and the ones that have failed seem to do so only on certain tubes. These tend to be cheap tubes that I did not purchase, but rather came with a used bike I bought, or were on another person's bike. While I don't have enough experience to say for sure, I think that these only have a problem with low quality inner tubes.Glue type patches are great, but only work well when you lay down the glue evenly and let it dry the correct amount of time. Many people don't realize that you have to wait for 5 to 10 minutes for them to set up, and I've found that the ideal time varies with the weather and brand, to the point where I find them less reliable. Plus, who wants to sit on the side of the road for 10 minutes waiting for a patch to get ready, mosquitos biting all over, the sun beating down? Miserable. If you really want reliability, you buy new tubes.If you use patches and want something to put in a saddle bag, I think these are your best option by a wide margin. They are very inexpensive, super small, quite reliable, and much faster and easier to use than glue-type patches.

Great for quick and easy puncture repairs on the road. So tiny and light you won’t even notice you’re carrying it!Better than messing around with a traditional vulcanised rubber and glue puncture repair kit by the side of the road - you just peel the backing off the pre glued patch and stick it on to the tube.Only meant to be a temporary repair, but personally I find these to be as long lasting as any other puncture repair and generally keep using the tubes with a couple of these patch repairs for months on end until I eventually need to change the tyres.

No se puede salir en bici sin unos parches y una bomba, es lo mínimo si no te quieres quedar tirado o a la espera de algún samaritano.Estos parches son autoadhesivos por lo que son más fáciles de instalar, además de que salta a la vista que ni pesan ni ocupan nada.Ya me han sacado de unos cuantos apuros personalmente y me ha tocado pararme a ayudar a algún desconocido que salía a la aventura sin parches ni bomba ni nada, lo que he aprovechado para recomendárselos para que la próxima vez no se quedara tirado.

Better than expected.
