I bought these to have a back up if I ever need them because the local bike shops are a rip off

These were good tubes, but the valve wasn't long enough for my rims.

Overall I can't say these are inferior to high quality tubes.I've only used one - and it's been fine for ~600 miles. Of course it's difficult to say how they'll behave over a year+, but I'll update this if they fail earlier than expected.The tyre levers that are included are pretty good. Worse than the dedicated blue Park Tools ones - and for tires that are tighter they might break sooner rather than later. Taking off/putting back on Continental Ultra Sport 3 tires w them was very easy.The valve does not seem to have any removable portion, or a mechanism for removal I'm unfamiliar with. Definitely not an issue if you're running standard tires though.

What I like about this bike tire tube is that it’s easy to install and comes with everything you need.

The most common repair in our bicycle and multisport shop is far and away flat tires. I always wonder when someone drops their bicycle off for a flat is - what they do if they are out on a ride? This is the one repair that everyone who rides any distance should be able to do. It's not hard either. All you need is a new inner tube, tire irons, and a pump.With that in mind, inner tube choice does matter. you need the right size for your tires and the valve needs to be long enough for the rim. These 700x23-25 are suitable for road and triathlon tires and for rims that are not deep dish aero. They fit my MAVIC KSYRIUM Elite rims with CONTINENTAL 5000 GRAND PRIX 25mm tires perfectly.The valve length of 48mm on these tubes is perfect for most road rims, other than time-trial triathlon deep dish rims, and the tune itself is well constructed with reinforcement around the valve, which is a common point of failure in cheap tubes. The manufacturer gives you a pair of functioning tire irons that are as good as the PARK blue irons. So with these inner tubes all you need is a frame pump or a CO2 dispenser and you will be able to fix your own flats.In my shop experience, there is little, if any, difference between big-name inner tube brands and others. "Off" brands are often just as good. So going to a bicycle shop for a name brand MIGHT not get you what you want - and will definitely cost you more. However, big box store "house" brand tubes tend to have more issues in our experience. Stick with tubes like these and you will be happy and save some money.OVERALL - This tube is fine, and I have mounted it on my race bike and ridden it with no issues. And would be confident enough to race on them. Keeper!
