MUTMAIN Polyester Piano Dust Cover For Casio & Yamaha All 61 Keys Keyboards Yamaha Psr-E363, E373, E473, E463, I455, I425, I400, I500 Keyboard & X870In, X8000In, X9000In Keyboard (61Pdc-Black)

Covers my Yamaha P225B 88keys digital piano from top to bottom and from all four sides.It has a healthy elastic lining which sort of packs the piano.Meant strictly for 88 keys digital pianos only. May fit 61 keys keyboards too but not sure.Not at all for upright pianos

Serves the purposethe material is waterproof.Quality is good. Material thickness and elasticity is good too.It also feels like a bike/ car cover because of the material.

Looks shabby, prevents dust but elastic very tight that may take some keys out. Wasted money!

Worst ProductPlease don't buyI bought it for the PSR SX900It didn't fit, and I asked for a replacement. I never got one.They cheated me by giving me the cover of a smaller keyboard.

For that money it's ok.Material is not so good.It becomes tight to fit a 61 keys piano.

Where I live, there's a lot of dust that builds up on surfaces over time. This cover has protected my keyboard keys perfectly. It's simple to use and fits just right.

Nice Fitting and serves the purpose. Material is also good with elastic to ensure the flexibility depending on keyboard size.

The media could not be loaded. This product won't hurt your pocket and provide superior protection to your music gear from dust. Fits just about right on my PSR S-710 from Yamaha. Yes, a pretty old model and still going strong.Hoping this amazing quality product will keep it alive for a few more years.Not to forget, this cover came in a cute little pouch of its own, which you can use to keep the power adaptor or anything that fits in it.
