Mooer Candy Footswitch Topper White

I've seen another product on youtube after I purchased this one, where it had a little screw to set the tention, this is something that this toppers do lack. I have a pedal where you cannot install those toppers at all and it feels like you can easily remove it. If it only had a good grip, I would have rated more.

Also why not have a glow in a dark version of it? This could have been such a nice thing to have.
