The Kato power pack has 1 distinct advantage and 1 distinct disadvantage.

The disadvantage is that it feels cheap. It's cheap plastic. It's very lightweight. The controls feel like they will break off at some point.

The advantage is the accessories connectors on the side. You can attach switches for turnout tracks just by pressing them on the side. They work great. There are various accessories you can power this way off a Kato power pack.

It does provide enough power to run  train fast and smoothly around your track. The neutral switch is nice so you can keep a specific speed dialed in on the throttle, but still stop your train.

If it wasn't fro the ease of adding accessory power controls to it, this would be a 3 star rating. If the unit felt a little more durable or was at least heavier so it didn't slide all over the place, it'd be a 5 star. I split the difference and gave it 4.
