These are pretty good controllers, especially for the price! My first thoughts are very positive. With all the basic features you'd expect from a Joy-Con, including vibration and the ability to play connected to the Switch or the included comfort-grip controller. I really like the design of the controller as it has special grooves that actually make it easier to hold than the original Nintendo Switch Joy-Cons. If you frequently have trouble holding the switch while connected to Joy-Cons, this is a good fix for that. If I have any complaints at all, it's that the Joy-Cons themselves are a bit lighter. This introduces a slight inconsistency when holding Joy-Cons while connected to a console. In conjunction with the included comfort grip, this is not a problem at all due to the weighted base. One of the biggest advantages of this product is its price. At half the price of the joy's usual cons, I expected a big drop in quality, but was pleasantly surprised. If you are in dire need of Joy-Cons, I would definitely recommend trying them out.
