They are backup tubes ready and waiting use.

I bought a 3 pack of 27.5 tubes July 2020. The core was removable as per product description. 1 of the tubes was defective. I contacted the Seller and they responded immediately. Communication was quick and clear. They replaced the product immediately. It was delivered before I saw the email where they notified me that it was delivered. In business, I see complaints or concerns as an opportunity to impress a customer. They really did so. I would like to rate customer service 6 out of 5.

Updated review as of 10/28/2019: it's unfortunate that I can't split the rating between the seller and the manufacturer of the product. The customer service from the seller has be fantastic. They obviously take pride in their operation and customer satisfaction is a top priority = 5 stars.I did receive replacement tubes with removable cores and they worked as expected; great value for sure. However, the packaging is still messed up. My first order was labeled "removable" but the actual product was fixed. The replacement order was labeled "fixed" but the actual product was removable...Original review:The tubes came in perfect condition, except that they did not have removable cores, which was the main reason I bought them. The tubes had solid seals around the valve and all the seams looked durable as well. If you don't need removable cores, these are a great option for you given the quality of the construction and the cost. These could have worked for me if the value stem was about 10mm longer to get past my Jet+ 4 wheels. As it is, I'll have to return them and try again. See pics showing advertisement of "removable core" and the fixed valve.

At first, I was thrilled with this purchase. These tubes seemed like a great value, they were the right size, what was not to like? When I changed a tire last fall shortly before I stopped biking for the winter everything seemed fine. I'm not sure if it's the midwest summer (or late spring) heat or what, but over the past few weeks, I have had to replace 4 of these in quick succession. Within a day or two, the reinforced area by the stem simply splits apart. I must have checked and re-checked my tire and outer tube 50 times assuming it couldn't be the tubes, but every one has a small tear by the stem even though nothing else caused it. Just this morning I was replacing one tube and the new one broke while I was filling it with air.So, it's a good lesson about getting what you pay for. These tubes seem like a great deal, but they definitely didn't last for me and I generally think the quality is poor.

The tube was excellent! I was just paying attention too much to the size and not so much. The valve, which was also excellent. By the way, that valve was spectacular. It's one of the best valves I've ever seen. I saw this valve.I said, wow, that's the most spectacular valve i've ever seen, but it's the one that I can't use...

Inner tube ws delivered on 4-11-20, Inner tube was installed and I rode the bike many times w/o problems, last time on 6/16/20. Today 6/24 the tire was flat, did NOT hold pressure, I took the tube out of the tire and quickly found the hole where the valve stem is attached to the tube. for the photo I inserted a thin piece of grass into the hole.With the defect at the base of the valve-stem, it appears that this inner tube can not be repaired.This is a “Freedom Bike DuroLite Tube 700 x 28-32 cI’ll see if I can find a replacement tube from a different seller/manufacturer.This tube came with a 60 mm valve stem, which my rim does not need. I wonder if a 40 mm valve stem could give a small benefit.Hey, I am getting practiced in changing inner-tubes. The 2 replacement tubes are the perfect size, and they hold air pressure very well. It’ll be interesting to see how many miles(Biking time) I get on these tubes, time will tell.Konrad, in St.Louis/MO

Ordered a pack of three and have had blows outs on all of them. One of them, brand new out of the box, never ridden, failed while simply under pressure on the bike (no rider weight, ec). Very lucky I was not riding the bike. I really liked these tires, great value for thicker tubes that used to last, but between this and my last order, do not think ill be reordering.

The price is right, they hold air well and have removable valves if you need to have that feature for adding extensions or if you’re adding sealant.They seem to weigh about the same as the average rubber tube and seem to work well with the tires to provide a good feel while on the road
