The 90-day replacement reminder was spot on for me—I noticed the difference in suction right after swapping these in. Comfort went back to normal and I’m glad the system tells you when it’s time.

I’ve been using these tubes for six weeks now and they’re still holding up great—no kinks or flattening, which was my main issue with the last set.

These tubes are a perfect fit and feel much more flexible than the ones I’d been using. I’ll definitely be swapping them out every 90 days as recommended.
