I bought these on Prime Day 2017 and can't say enough good things about the process. First discount, it came 1 day after purchase. Better than 2 days shipping which is incredible given the volume of orders processed and shipped on Prime Day. Second, the main focus of this product is to make each joystick more convenient for playing multiplayer games like Mario Kart. 8 deluxe. They do it amazingly well. I avoided playing Mario Kart with friends until I bought these pens because it just isn't convenient to use a single Joy-Con. It feels so small in your hands and you're basically forced to use it with the wrist straps attached as the triggers barely work without the strap. So, for starters, these buttons are the size and shape of a PlayStation controller, so they're very convenient. The start buttons are much easier to press when depressed; They're even easier to squeeze than a wrist-strap Joy-Con. I tried pressing them from different angles and each time they responded perfectly. Most of the negative reviews for this product were a) the joysticks fall out of their pins or b) the trigger buttons don't respond very well. It's safe to say the joysticks are tight, but they're not so tight that they're difficult to remove. My 4 year old was playing with me and waving the controller around and the joycon didn't even budge. The trigger buttons, as mentioned above, work surprisingly well. They're better than standard Nintendo Joy-Con accessories like wristbands. There is nothing about this product or its delivery that makes me give it less than 5 stars.
