Price is reasonable and tube is really light. There are lighter tubes out there, but they are going to cost you more cash and may not be as durable. I only weigh 170lb so no problems with pinch flats or cuts here. Reliable as they come. Would buy again, would recommend.
Bought these tubes because I wanted lighter weight tubes to use with sealant. Many other lightweight tubes (i.e. Performance) don't have removable core valve stems, which you need to get sealant in. These do. They've worked out fine. Weight was just as advertised.
