Since I'm very hard on inner tubes (make that my mt bike and offroad riding habits) I was happy to find a sturdy pair on Overstock.com for a low price. After adding the requisite amount of Slime I have duly given my new tube a thorough pounding and it has held up perfectly. I will be shopping for more bargains on the big "O" in the future.
This little gem fits great behind and under my bicycle seat. It was the better deal because you three cartridges. I wouldn't buy it without the case. Very happy how it dosn't interfere with my ride. The description is very accurate and is exactly what I ordered.
