The silicone strip fits my Yamaha keyboard - not perfectly flat between the back of the keys when fitted but that isn’t a problem as it does not interfere with the keys.
Easy to fit and the quality seems good.

Didn’t fit my midi keyboard, this is designed for something with wider keys. The product itself seems to do what it’s supposed to. I just didn’t have the right keyboard.

Help a lot

A must have if like me you keep forgetting the notes this handy strip fit my keyboard perfectly making my learning a more pleasurable experience they are wipe clean and do not do any damage to the keys they are placed on, I have ordered a further set for a friend who also thought them to. Be a good idea very satisfied would recommend to others good value and re usable.

WHAT IS IT FOR?

It's a three-part overlay for a full size electronic keyboard (synthesizer, electric, electric organ?), covering up to seven octaves. You lay it on the keyboard (in the gaps) to help you find (and learn) the right ones while learning!

IN THE BAG

You get a small ziplock bag containing there keyboard overlays, horribly tangled and scrunched up. They look truly terrible; not a good start.

SETTING UP

This is quite simple:

1: Open the bag and spread out the overlays on a flat surface. Be careful that you don't make any twists worse.

2: Leave to settle for a few hours in a warm environment

3: Lay the overlays in the correct order (1, 2, 3 reading from left to right) on your keyboard

4: Make sure that you've got the Middle C label on the Middle C key!

5: If your keyboard is less than seven octaves, you can cut off the excess at each end - or leave it dangling as I have.

The photos are for my 5-octave (61 key) Casio CS1X, which the overlays fit very well.

USING

Not much to say really:

* The overlays are quite sturdy, thick-ish rubbery plastic, so they should last

* The legends are very clear, in multiple colours - helping me hunt and peck

* They are an exact fit for my keyboard so they don't interfere with the keys in the slightest

* They still aren't completely flat, but that's an aesthetic/cosmetic quibble

BEST BITS

+ Good quality rubbery plastic
+ Clear printing, easy to read
+ Easy to install, good fit
+ Up to seven octaves (88 keys)
+ Not expensive

WORST BITS - nothing much

- They arrive in a terrible mess - improve the packaging!
- Why three separate parts, why not a single overlay?

(I presume the main overlay is sold separately for small keyboards and they add the top and bottom octaves to make seven, but manufacturing economies like that shouldn't dictate how a product is designed.)

CONCLUSION

An excellent keyboard overlay in three parts that fits my keyboard perfectly. Up to seven octaves (88 keys). A bit annoyed that they arrive in such a tangled state, in such cheap packaging, and why is it in three parts? Four stars
