Bought them as spares & haven't used them, so I can't comment on durabilityperformance. I bought them because of threaded stem, weight, & quality rating from other users. I like the threaded stem, less hassle inflating, & pretty much eliminates valve stem leak problems caused by the stem moving. My current tubes are threaded stems & I like them.
I've been using these tubes for the past 1-2 years almost exclusively. No weird issues or anything indicating lack of quality. I have Vittoria's latex tubes in my nice weather road wheels and these in everything else.
OK I'm not sure that this tube is THE lightest out there, but it's pretty darn light! Like anything Vittoria, it's quality through and through. It's just a tube, for sure, but when you're looking for light weight and quality, this is it!
These tubes have held up as well as any for me. They are very light, but I have not noticed having more flats than with heavier tubes. I like the 51mm valve length. Ultralite tubes are usually more expensive, so these were a good buy at [$] each. I usually get 4 or 5 at once, to take advantage of an extra quantity discount if offered.
Switching from a standard tube to Vittoria's ultralite, you can feel (and appreciate) the difference. My concern about increased flats with these tubes has, thus far, proven baseless. The 51mm threadless stems are perfect for my 35mm-deep Aeolus3 rims. Stockpile 'em!
A perfect match with my 38 mm depth rims, and I really like that the valve stems aren't threaded for the 51 mm tubes, I find the threads tear up the gasket in the pump head.
tube blew up twice without even riding. too thin
Sometimes lightweight tubes can get caught in the tire's bead during mounting, which can cause punctures during inflation. Using a little talcum powder can help with this problem. If you're experiencing other blowouts or punctures with no apparent cause before riding with the tube, you may have a defective tube.

I got these because I can put an ounce of Stan's sealant in them due to the removable valve core. The rubber and construction seems pretty much identical to Michelin tubes which I've used for years. I love the cool brass thread less valve stems and general Euro feel to the product.
They seem a bit small in circumference when you put them on but down the road that may overcome the problem of stretching out too big after they've been on before.
