Customer Reviews
Good trainer, shipping was fine
I grabbed an O2Trainer breathing exerciser last week. It got here pretty quick, took about 4 days to get to me in Texas. The device itself feels sturdy, not flimsy or anything. Been using it for my runs and I can already feel a difference in my breathing capacity. It's easy to adjust the resistance too. Overall, I'm happy with it and it was a good purchase.
Solid trainer, some minor delays
I ordered the O2Trainer breathing exerciser with a travel case. The device itself is very well made and has been helpful for my training. It feels robust and the resistance levels are easy to switch. My only small gripe was shipping took a bit longer than expected, about 8 days to reach me on the East Coast, which felt a little slow compared to other online stores. Customer service was responsive when I inquired about the delay, which was a plus. Overall, a good product, just wish delivery was a touch faster.
Great value on the O2Trainer Kit
I was looking for a breathing muscle trainer and compared a few brands. The O2Trainer kit caught my eye because of the discount they were running. I managed to get 15% off, which made it a really good deal compared to others. Shipping was free which was a nice bonus and it arrived in about a week. The kit included everything I needed to get started, so I didn't have to buy extra parts. For the price I paid, I feel like I got a lot of value. Definitely worth the money if you can snag a deal.
Reliable and consistent product
This is my third purchase from O2 Trainer, this time I needed a replacement O2Trainer mouthpiece and some new resistance caps. As usual, the order process was smooth and shipping was efficient, arriving in just under a week. I've always appreciated the consistent quality of their products. My original O2 Trainer is still going strong after a year, and these accessories feel just as durable. It's why I keep coming back for my training needs; they deliver every time without any hassle.
Good product, fast shipping
Ordered an O2Trainer. It shipped quickly. Product works as described. Easy to use. No issues.
