GOOD STUFF: 1. Features 19 songs in varying difficulties 2. 1-5 Speed mods can be selected (But sometimes two speeds dissappear depending on the selected song and chart) 3. Supports TWO player mode. 4. The pads extend out from the cabinet 5. Music isn't actually that bad for unlicenced music. The songs also last 2-3mins 6. Highscores are saved for each chart and chart difficulty. 7. Runs on USB power as well as batteries. Hopwever, if your batteries die, the phone app will need restarting. BAD STUFF: 1. The app INSTANTLY requires a login to play. This is provided when a machine is purchased. NOTE: You can give these to a friend and it'll work. There is no device limit. 2. The graphics are inconsistent. The pad has a classic Pump It Up yellow arrow, but in the game, it's a red circle. The pad has a classic Pump It Up red arrow, but in the game, it's a pink arrow. 3. The branding is inconsistent. They contracted the app dev out to another company (Lemon On / Ranger Jianghu / etc / etc) and they used whatever logos and images they left like. It was a bit tricky to work out which app I needed. It even differs between app stores and countries. It's madness! Even the name of the product different from the app name. It's really weird. 4. There haven't been any real app updates since it's initial release with a few initial bug fixes. We are on v1.1.6 at time of writing. Still 19 songs. Still no real changes or updates. 5. No licenced songs. Can't really be that surprised though right? 6. If you accidentally press a side button on the phone, like Bixby, the app will need restarting. It gets caught in a bluetooth connection loop. 7. No doubles mode. No online leaderboards. NOT GOOD OR BAD?: 1. It talks to your phone via Bluetooth THOUGHTS? I feel after a couple of years, the app will go offline and we'll have a useless machine (In terms of playability) unless somebody steps in and creates a custom engine/app for it. Otherwise, it's pretty good.
