They worked great, good quality, and cheaper than purchasing just one I could find at a department store.

Replacing a Schwalbe 26x4 tube due to a puncture. These are much thicker and utilize a Schrader valve. My eMTB is a fat bike and I drilled my wheel accordingly to fit these tubes. 21/64 drill and a round file did the job with no decrease in structural integrity on the already wide wheel. I was also tired of the Presta valves which really don't have any business on an MTB or in the USA. Presta valves bend easily and are a pain to get the correct pressure, plus there's no pressure gauge that fits for them other than the gauge on the pump. These tubes are substantial and a fair bit heavier, which is the trade off when constantly getting punctures from puncture weed. Yes, I expect a slight decrease in electric assist range.

I previously posted a review that this purchase was a 1-⭐ buy due to the bike tubes being received damaged by what I perceive was a manufacturing anomaly. Such can happen to any product, from any manufacturer, and I was frustrated because I had delayed installing the tubes, and discovered the damage after the return window had closed, but that is my bad. After seeing my one-⭐ review, Ultraverse immediately refunded the purchase price w/o my asking given they have a 100% customer satisfaction policy, and that is a ⭐⭐⭐⭐⭐ response! I most definitely will be purchasing from them in the future. Thank you, Ultraverse Support Team!
