If you're a clarinet or oboe player, you know how much strain your thumb can take during long practice sessions. That's where the Thumb Rest Cushion from Duo Music Korea comes in. I've been using it for a few weeks now, and here's my honest take.

The first thing I noticed was how soft and cushiony these silicone rests are. They mold perfectly to your thumb, providing immediate relief. After an hour of playing, my hand felt significantly less fatigued compared to before.

I love the curved design - it really does fit your finger naturally. The two-color option (purple and blue) is a nice touch if you want to match your instrument's aesthetic.

However, there's one major drawback: the non-slip claim doesn't always hold up. Like one reviewer mentioned, I did find myself readjusting more than I'd like during intense playing sessions. This can be frustrating when you're in the zone.

Durability seems good so far - no signs of wear after regular use. They're easy to clean too, just wipe with a damp cloth.

While most users (including myself) find these incredibly helpful for thumb pain relief, they might not work for everyone. If you have particularly sweaty hands or play very vigorously, the slipping issue might be a dealbreaker.

Overall, at this price point, they're worth trying if thumb pain is affecting your playing. Just be prepared that they might require occasional adjustment during use.
