Was able to fix my 30 year old handcart that blew a tire. Much cheaper than what HF wants for a replacement tube.

Quality and price are both very good!

Product arrived in a soft envelope as you see in the photos. The kit is complete for 2x inner tube replacements on a common hand truck sized tire, but make sure you read the outside of your tire to make sure it matches the item description. I like that the kit includes a valve stem removal tool and some spare screw-in valves, but it's only been a few times in my life that i've had to replace a valve, so just put it somewhere you'll find it again. Apart from that, taking the old tire off of the rim is the hardest most frustrating part of the process, and the need for special tools that you may or may not have, which is where the highest chances are you'll accidentally put a hole in this new replacement inner tube. I was being as careful as I thought I could be and still managed to put a hole in one of the tubes, so i'm a bit disappointed that i'm now down 1 replacement tube because it didn't survive the process of putting the tire back over the rim. But that doesn't speak to the kit and inherent value it offers, which is good. Just make sure you tires are still soft and pliable before you do this job, otherwise you might want to consider other options (e.g. complete replacement non-inflatable tires or use of tire sealing compound)

I bought these to replace the tubes on my UGV, and the sizing seems accurate and so far they are holding air well. They seem a tad thinner than the tubes that came in the tires I have, but so far they are holding air well and they seem to be decent quality. I will update if they start to leak or if they fail, but so far so good! I'm quite happy with these. I don't buy tubes like this often, but at $12 for the pair at the time of this review they're a good value.

It's surprising what small tires cost and I have always had bad luck keeping the beads sealed on equipment like hand trucks, wheelbarrows, etc. In this case I had a nice mobile hose reel cart with good pneumatic tires that refused to hold air because of the bead. I tried gooping up the rims but it never seemed to work. So finally I decided to go the innertube route. Unfortunately I'm not as handy with tires as I thought I was and ended up taking the wheels down to the tire shop where a couple of guys working together got these tubes installed in about 5 minutes. Problem solved! So I couldn't rate it on "easy to install" because it didn't look easy to me--but that has nothing to do with the quality of the product. It feels like good thick pliable rubber and I'm guessing these tubes will last the life of the cart. Don't keep putting air in your hand truck or wheelbarrow tires, spend just a few bucks and put tubes in them!

The tubes looks cheaply made . I got two and one exploded while inflating . Spend a little more and get something more reliable .

This 2 pack of inner tubes from Merryard Outdoor is priced much lower than the local hardware (saving money is a good thing). It's like getting an extra inner tube for free. If you've never replaced one of these before, the bent valve stem is a definite must have. So much easier for checking pressure and inflating these small tires. I have a snowblower without the bent valve stems and there's a big difference. I like the included valve stem tool to insert the stems. It can also be used to clean the threads on the valve stems. This worked perfectly on our ancient wheelbarrow wheel. Now I won't have to pump it up before each use. A great replacement at a great price, plus you get an extra for the shelf!

I've fought with a slow leak for a while now and often was just runnin' it lean. No longer, for this 2 pack is a flat tire repair in under 15 minutes. These replacement tubes were the exact size match for my hand truck, right down to the angled metal valve stems. Great quality tubes too, better thickness than the stock tube I removed. They even came with extra valve parts, caps and a pretty decent valve tool. What's not to like? Nothing - all 5 stars land here.
