We got one a couple weeks after launch, I've enjoyed Blaster Master Zero. I ended up beating Breath of the Wild on the Wii U instead of the Switch because we weren't initially planning on getting one. Snipperclips is great too. 1-2 Switch is ok in short bursts, and Super Bomberman was a bit of a disappointment so far, although I haven't tried it with the recent patch.
My daughter has played Zelda on it in the car quite a bit on some 2-2.5 hr trips, and we've had no issues with battery life.
I think I'm really going to play more once Mario Kart arrives this week. I'm really looking forward to having a good battle mode again, unlike the crap battle mode they gave us in Mario Kart 8 on the Wii U.
