I've used my recently purchased MiniBrute for the 1st time today. I'm very impressed with the possibilities of having a a tool of this magnitude in our studio. After one I packed the MiniBrute away in its box. I lifted the front of it to place the power cord underneath and notice that the Middle "C" key was not aligned with the rest. I pressed if softly to see if would go all the way down and noticed the key next to it "B" was stuck and would not press down at all. I plan to send my MiniBrute back. I'm very disappointed by this as I had great expectations for utilizing it. It's an amazing machine and should be made more durable. As I read through this forum, I noticed that others are having issues with the MiniBrute's durability. I don't know if I'll get another one. This was my second one. My first one did not last more than a couple uses.
