Not extremely satisfied.

I've had all of the other problems mentioned in these reviews. Had one brand new tube split at the seam with less than 20 miles on it. Had several pinch flats. We also run slime. Never had an issue with Moose heavy duty tubes. I thought it might be the artrax tires because my dad is having the same issues with flats since he put them on. We're going to switch to another brand of tire and tube and see if that remedies our problem. I will not be purchasing these tubes nor artrax tires again.

I bought this tube because I am racer and I use the tubes all the time. they were the best tubes out there but here recently they have been coming in with holes in them. maybe they can get it together and make them with no holes, but if they can't we will be having some problems, I don't want to spend my money on a product then not get my money back for it being a terrible tube

Update to above post

Pinch flat. I may try a Golden Tyre G-Mousse. This tube may work just fine with roots, but a rocky boulder race not so much. Unless you ride and dodge rocks. I prefer to SEND IT!

When it says ultra heavy duty they mean ULTRA HEAVY DUTY. It is super thicc and you don’t have to worry about ever pinching the tube. Overall it is a really good tube that is practically guaranteed to never get a flat.

Not as good as I hoped

I have normally used Moose heavy duty tubes. Decided to think more economically and came up with one of these. Raced a GNCC at Snowshoe, which has boulders the size of basketballs and smaller everywhere. While I did finish the race, it ended on a flat. I have yet to break the tire down and see exactly what the fault was. Will update when I do. I'll spend my next dollar on a Moose.

Stranded on the Trail.

Bought this tube as it was the most heavy duty one that MotoSport carried. Have 3 rides on it. Got a flat on the trail and was stranded. Never have I ever had a flat that was not caused by hitting something and puncturing, or pinching during install (which is apparent during fill). Got the bike home and pulled it apart to find the molding line in the tube is separating into a slit. You will see in the Photos.The tube felt promising during installation, but my suggestion would be to buy a different brand. Never have a problem with Artrax or any regular duty tube. Just though the thicker tube would be better.

To thick would not fit into the tire correctly.

I bought the size that matched my tire size. Being the tube is a HD tube its extra thick and would not fit into the tire correctly forcing me to purchase a local one so I could ride.

I got one and a half rides out of this tube.
On the second day it split along a seam.
Cheap tubes!!! Badly made.
Will never buy this brand again

Best tube I’ve used!

I’ve been running these tubes front and back, the bike sees just about every terrain and I was getting a lot of pinch flats from riding creek beds with tons of rocks and roots,switch to these tubes and I haven’t had any issues. Great product little difficult to install due to the thickness but over all awesome tube!
