This is just a quick update, a year and a half later everything still works well and it gets constant use. I bought this bundle to go with my Roland kit as I was trying to keep costs down. The set up was very simple. The kick drum pedal works really well , I haven't adjusted anything it just worked well out of the box.
The throne is perfectly adequate it's comfortable even after two hours of playing. If I had one criticism it would be the stability. When it's raised to the maximum 2 heights it does feel quite wobbly, but at the height I have it, it feels fine.
Overall, very happy, I'm sure there are better products, but for the price I think the throne and pedal were really good value.
