For something completely different to my usual impressions, I'm doing a mini review of the Hori Split Pad Pro (my version is the Pac-man version if it matters). IMHO this is likely not worth it overall unless it has a heavy discount. This product replaces the joy-cons when you have the Switch portably and not docked. They're bigger than the joy-cons for sure, and the comfort is a little better, but similar for me.
The quality of these is pretty alright, but not worth $60 for sure. I got about $11 bucks off and feel a little bit miffed at what I paid. First the joysticks on each of them is decent quality. They are sensitive and seem to play better for action or platform games. The joy con joysticks aren't terrible, but feel a bit small and harder to use. The L/ZL and R/ZR feel a little bit better, but are a bit more spongy. They don't press super well, but aren't terrible either. I think they do feel better than the tiny ones on the joy cons. The d-pad is a million times better than that 4 button abomination from the left joy-con. It works so much better, and if a game uses a lot of this, it helps a lot. The smaller buttons are okay (+, -, home, screenshot) and similar to the joy-cons. What is likely the biggest negative are the face buttons (a, b, x and y). These feel very mushy and not as responsive as their joy-con equivalents. I play a lot of Picross and sometimes things would not register as well with these. The A button feels the worse as it's on the downward curve of the controller. These buttons are passable, but don't feel amazing. Also I need to mention that these are light and work off the Switch's battery. They don't have rumble (who cares), gyro controls (not great) and don't act independently outside the system. For these misses I feel these are overpriced.
Overall I like the controller enough. The better joysticks and d-pad are worth it, even if some of the other stuff feels a bit mushy. I didn't mention you can do turbo and a custom button on each side, but I haven't used those features. I don't love the joy-cons myself, feel they can be a bit small, and have one of the worst d-pads ever on a controller, but they're passable. These make them feel like joy-con+ instead of an amazing extra controller. These do make it easier to hold and it works better for some heavy action titles, which weren't amazing with the joy-cons, but they're just likely too expensive. Around $25 at most would be my recommended, but they're not bad either. If this had better buttons I would say to get it even with a higher cost, but with their missing features, I would mainly recommend it to those who want bigger joy-cons and play portably often. Not bad, but in need of a v2. 7/10
