The Nintendo Switch Pro Controller is currently on sale for just $59, that's good for $69 off of its regular price, and makes it a great time to pick one up. This is a great addition for anyone that has picked up the Nintendo Switch recently, as this controller is a bit more ergonomic than the joycons that are with the Nintendo Switch.
The Pro Controller is a great pickup if you are using the Switch connected to a TV or a larger screen more often. It's going to allow you to take your gaming session up a notch, as it is more ergonomic as mentioned already. It does also include HD Rumble and amiibo support in the controller, so you won't be missing out on anything. Like the Nintendo Switch, it does also charge over USB-C. This is great because you can take one charging cable with you and be able to charge both devices with the same cable. Definitely a good thing here. Battery life is pretty good on this one, as it can likely last you a full day and then some of playing. So if you have a long flight, or maybe a long ride on AmTrak, you can bring your Switch with you and play all day and then some.
