Bike Inner Tube with Slime Puncture Sealant, Extra Strong, Self Sealing, Prevent and Repair

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.

I'm a stickler when it comes to anything always nitpicking everything, looking for any flaw i can and despite the fact that there not solid rubber inner tubes they are pretty good! before i bought these i was attempting to have BELL custom make me solid rubber inner tubes but as you probably guess it was futile, so i decided to get the next best thing Hesitantly of course and reluctantly already thinking "its just a waste of money for something that isn't absolutely flat proof!" cause before i was getting flats literally every other day because i ride a 90Ib E-bike and i already weigh over 175Ibs and last i checked there's not a weight rating on any bicycle inner tubes and that's because no one expected there to be electric bikes riding around so naturally there's not any custom inner tubes capable of supporting the extra weight without blowing out or slicing into the inner tube from the rims due to the sheer weight but to my surprise these slime inner tubes have held up quite well and I've had them for roughly 3 weeks now, i even bought a big bottle of slime just in case and i haven't had to use it once heck its still in the box unopened if that says anything?
