Yamaha S90 Split Keyboard

I use this dust cover on my Yamaha s90 (90 keys) keyboard, and it fits great. It is snug, but not choking, and it could be expanded even more if needed. I haven't had it long, but it seems durable as long as you don't get it caught on anything really sharp.

Perfect inexpensive coverup for your Yamaha or other same sized keyboard.

I bought this for my Yamaha keyboard - fits perfectly and looks great!

Covers my yamaha np-30 keyboard perfectly.

This Yamaha Keyboard Bag is just great. It's compact. It's a perfect size for my keyboard to fit in. It protects it on all sides.

Very well made - correct piece form my Yamaha EW425 keyboard.

Got this cover and it fits really well on my Yamaha-45 [ 88 note keyboard ]

The keyboard cover fit my Yamaha keyboard perfectly. ... Very satisfied customer.

This product -- especially when combined with a split ergonomic keyboard -- helps to reduce stress on your wrists. Clutching the mouse puts a lot of stress on the muscles in your forearm. But you roll this big trackball with your open hand. Instead of clutching the mouse button, you can simply tap one of the big programmable buttons with your thumb, and the mouse locks and drags until you tap the button again, when it releases. The scroll wheel is terrific. It seems like an afterthought but I use it all the time. I like this product so much, I bought one for my business partner for Christmas. Just like the split keyboard, people who sit down at my computer and use the trackball for the first time hate it. But if they use it for more than one full day, they end up loving it.

This is a great trackball. I use it between the two halves of a Kinesis Freestyle Pro split keyboard to reduce horizontal arm movement. The front has legs which can be raised to create a flat profile (but not that it sits fairly high in this orientation). Also note that there is no horizontal scroll capability on the scroll wheel if that's important to you. For me, these aren't issues and the huge trackball and click buttons make it very easy to use.
