Very useful
Used for 2 to 8 weeks
Used this on a long ride when I got a puncture. It was far easier than trying to fix the puncture with the limited tools I had available. The gel got me home (30km) without any sign of a problem. I fixed the puncture properly at home and have had no issues with the tube.
Definitely worth having one of these for emergencies.

Ive tried this product twice and both times it failed to stop even a small puncture.
Response of the brand
Thank you for your feedback regarding this item. I am an avid user of this item and it does have some limitations (size of the hole) but as long as it is applied correctly (no pressure in tyre, tube and can pointing vertically when applied) then it should work fine.
If you need more assistance, please contact our loyalty team who will be more than happy to assist.

Crappy Instructions
Used for 1 week or less
I found the instructions after a few minutes...back of wrapper...but they are not very good. They're too small for me to read even with special glasses to increase the print size. There are also too many diagrams by way of explanation and these are not always clear. I suppose they don't have written instructions because those would be more expensive to produce. Hence, I would NOT recommend this product.
Response of the brand
Thank you for your feedback regarding the instructions. We sell this item in all European countries and the diagrams are used for this purpose. There is also a QR code you can scan which takes you to a youtube film demonstrating the item in use.

I use this item and here are a few pointers I have picked up over time. 1) Make sure the tyre is fully deflated before use. 2) Valve must be at the 12 o clock position when filling 3) after securely attaching the sealant to the tyre valve the transparent tube and canister must be as vertical as possible (12 o clock position) and in line with the innertube valve. 4) once content has been emptied and can removed, spin wheel for 20 seconds to spread the foam evenly throughout the innertube.

Easy to use and effective

Tried once, worked once! A lot easier than swapping out a tube in the rain.
Why are the instructions not on the product?
Used for 1 week or less
I bought this on my lunch hour, rushed back to work to use it. No instructions, so I had to just try it. Most of the foam went everywhere - it inflated my tyre but I have no idea if it worked, I’ll have to just keep my fingers crossed until I finish work, and then I’m in a big rush to pick my daughter up so if it hasn’t worked I’ll be seriously inconvenienced! Put the instructions on it (not just on this website)!
Response of the brand
Hello,
The user instructions are found on this can. You simply need to peel back the label to uncover the user guide.
After using this item a few times there are a four fundamentals to respect.
1) ensure there is no air in your inntertube prior to application.
2) your innertube valve needs to be pointing downwards (12 o clock)
3) both tube and can need to be totally vertical (no kinks or bends)
4) remove the metal valve/hose from the innertube as quickly as possible to avoid spillage

Got me home!
Used for 1 week or less
Had a flat tyre, used this product and MTB tyre inflated sufficient to continue on ride. Will need to replace tube, but as a get you home accessory - fantastic.
Good idea- shame it does not work!
Used for 1 week or less
I bought this product hoping to find an easy solution to punctures. I have tried this on two occasions. On the first- the foam went everywhere and when I unscrewed it my inner tube valve was unscrewed with it. Result- foam party! The second time- Screwed it on, filled my tire, tried to unscrew- poured out- foam party 2!! Absolute rubbish!
Response of the brand
I'm sorry to read that the foam came out so quickly. Generally speaking, as long as the canister and tube are held vertical (with no bend in the tube) then it should not leak out in any significant amount. I would agree that some slight of hand is required to swiftly unscrew the valve adapter.
If you are not happy with the item, please feel free to return it for a replacement.

Great value
excellent
Used for More than 1 year
I have used this a few times it's never let me down. Grew for getting you going quickly without having to get out the tye levers. Stays hard for approximately 36 hours, then best to replace the tube.
