Yueyinpu Bluetooth Page Turner Pedal $25.75 ($20.60 with 20% off Coupon) + Delivery ($0 with Prime/ $59 Spend) @ Yinpu Amazon AU

This is a great little Bluetooth page turner pedal that is designed for musicians who read sheet music from a tablet/PC/iPad and want to turn the pages without taking their hands off their instrument.
My son has been using it since 2023 - the pedal is very responsive, silent and just works as you'd expect.
He mainly uses it with a piano just to the left of the piano pedals at a 45 degree angle. Occasionally uses it with violin.
Used it at many gigs: school, clubs, even the Sydney Opera House.
He uses it with a Windows 2-in-1 laptop running enScore(apps.microsoft.com), a free Windows Sheet Music Viewer app but it should work with most programs since it's just a Bluetooth keyboard with 2 keys.
It's USB-rechargeable and the battery life is great - has never run out during a performance and he's played 2 hour gigs.

On my account I had a 20% coupon (expires 2025-02-19) bringing it down to $20.60 which is slightly cheaper than when we bought it in 2023 and well down on the usual $45.99.
If you use discounted gift cards you'll probably get change from $20.
There are now 2 models. This one is now called "Classic" and there's a newer, larger, pricier "Plus" one.
My son wears US size 11.5 shoes and he is very comfortable with the Classic pedal.

I'd set up a 3 camels notification to know when it dropped to this bargain level so I could order another for a piano teacher friend. Arrived next day in metro Sydney.

BTW I have soft spot for this pedal because after updating my Amazon review I got invited to the Vine program.
