Review on BelugaDesign Pastel Button Caps and D-Pad for Nintendo Switch Standard OLED Joy-Con Controller Covers - White, Compatible with Directional & A/B/X/Y Buttons by Cee Pouncy

Looks good. Ease of installation. Great for casual games like Animal Crossing and Breath of the Wild, but I wouldn't count on it for something like Smash as sometimes you get input sentences instead of one. It's not the product's fault, it's just the best you can get without actually installing the right cross. If you need a suitable cross you can look at Hori brand left hand joysticks or just buy a suitable shell and install it yourself if you know what you are doing. Other than that, it's a great alternative.
