Work Well
I think these are good tubes, but overrated. The "no more flats" is certainly not true. But at the same time, they have worked well for me in about five thousand miles of riding. Here is my experience: They do get punctures the same way as regular tubes, but if you are moving along the puncture will partially seal. I also use very tough tires (Continental Gatorskin). You can see the green stuff ooze out at the site of the puncture before "sealing". On a recent occasion, my tire went completely flat at a very inconvenient location. I pumped it up instead of trying to replace the tube which I carry (not the slime type). I pumped and spun the tire as fast as possible; repeating several times. This got it up to maybe 60 psi which was good enough to ride back to my car some 30 miles away. When I got there, the tire was still rigid enough to continue riding on. But at home after a few days, the tire was down fairly low, although not completely flat. I replaced it at home, which is a lot easier than doing it on the road, especially since I find it difficult to take the tire off the rim due to arthritis in one of my hands. Another problem I encountered is that the green goo clogs the valve making it hard to inflate the tire when it is low. I take care of pressure before leaving home. I found that if you let out some air the green goo is flushed out of the valve. Then you can re-inflate the tire more easily. I would not recommend risking inflating the tire after you have arrived at your starting destination. Let me say a little more about the flat tire problems on road bikes. I found that the aforementioned Gatorskin tires take care of most of the puncture problems. They resist all the big stuff like small nails and glass shards. What gets through them is fine wiry debris that is left from shards of shredded steel belted tires that are on the road side. In almost all my flats, that's what I found. These wires get through the kevlar and cannot be seen or removed from the outside. Hence requiring a removal of the tube before the tire can be cleared and restored. No tube will seal itself permanently in this situation. So, if you use the puncture resistant tires, these tubes will essentially get you home, but you still have to replace them. For me, that is worth it, so I am giving it 5 stars. I know riders who change tubes out in 5 minutes - for them it is not worth it because these tubes are heavy and expensive. Addendum: After I wrote the review, I had another flat with these tubes. The tire went completely flat after about 50 miles of riding. It was pumped up at the start to 80 psi. I was not far from the end, so I pumped it up and it held for the next 1/2 hr of riding. It still had good pressure, but the next day it was flat. Upon examining the tube at home, there was a small hole in it. It did not seal, or whatever the mechanics was, it is not able to seal to give you more rides as long as the cause is not fixed. Then you can patch it up as you would any other tube, but I just throw the punctured ones out because they can never be relied on. I am still using these, because they are better than normal tubes for my circumstances and needs.

Incredible. Self repaired a large hole and didn't need to replace
There was a huge rip in my tire which caused the tube to end up bursting the hole was probably larger than you would normally get from a puncture and it sealed itself after just a few seconds it was absolutely amazing the tire did not end up deflating all the way despite the large burst in fact I never ended up needing to change the tube I just aired it back up to full pressure and keep using it like that after replacing the outer tire.

Good but seam busting problems.
Seam-busting problems. This seems to be a good "thinner" tube, there are thicker ones out there. It's overall good I just had trouble after about 500 miles the seam blew out. Always carry 2 or more with you just in case!

Decent inner tube
I use these in wheelchair tires. They do add a tiny bit of weight but nothing that should affect performance. I do recommend that when adding air to an already inflated Tire that you place the valve stem at the top of the wheel and give it a few minutes for the Slime to move away from the valve stem. I experienced some slime leakage from the valve stem when adding additional air with the valve stem at the bottom of the tire.

Kid proof
I recently purchased the Slime Bike Inner Tube for my bicycle, and I must say that it has been a game-changer in terms of preventing flat tires and ensuring a smooth ride. This innovative product has provided me with peace of mind during my cycling adventures, knowing that I have added protection against punctures and leaks. One of the standout features of the Slime Bike Inner Tube is its self-sealing properties. The tube is pre-filled with Slime, a special sealant that automatically seals punctures as they occur, preventing air from escaping and keeping my tires inflated. This has saved me from the hassle of dealing with flat tires while out on the road or trail. The installation of the Slime Bike Inner Tube was straightforward and hassle-free. It fit perfectly on my bike wheel, and I appreciated the added layer of protection it provided. The durable construction of the tube gives me confidence that it can withstand rough terrain and everyday use without compromising its performance. I have noticed a significant reduction in the number of punctures and flats since switching to the Slime Bike Inner Tube. The sealant inside the tube effectively seals small punctures caused by thorns, glass shards, or other debris, allowing me to continue my ride without interruption. Overall, I highly recommend the Slime Bike Inner Tube to cyclists looking for an effective and convenient solution to flat tires. It is a reliable product that delivers on its promise of added protection and peace of mind on the road or trail. With the Slime Bike Inner Tube, I can focus on enjoying my ride without worrying about unexpected punctures or leaks.

Su primer salida y a los 80 km una pinchada común que nunca se reparó, jamás se auto-selló (o auto-curó). Lo peor fue que traía puesto una banda anti-pinchazos y ni eso ayudó. Quise poner un parche y nunca pegó por que el Slime no permitió actuar al pegamento del parche. Terminé mis 290 km restantes con una cámara común y hasta más ligera y más barata que ésta. Quedé decepcionado del producto y fue un gasto inútil. ...y compré 3! (-_-) Quiero mi dinero de vuelta!

Dieses Fahrradschlauch finde ich genial! Leider habe ich kein Foto mehr, da es sofort in das Fahrrad eingebaut wurde. Seitdem erfüllt es seine Funktion einwandfrei. Der Schlauch ist dick, von sehr guter Qualität, und sogar der Herr im Fahrradservice, der ihn ausgetauscht hat, war sehr beeindruckt. Wenn ich irgendwann wieder Fahrradschläuche kaufen muss, werde ich definitiv diese nehmen. Ich kann sie jedem wärmstens empfehlen.

Incroyable ! J’ai crevé 2 fois avec la même chambre à air. J’ai continué de rouler le trous c’est bouché tout seul et les deux fois j’ai pu rentrer avec 80% d’air dans la chambre à air. J’ai regonflé en arrivant. Ça tiens toujours. Super produit. Je n’aurais jamais cru, je recommande vivement.
