I love the bluetooth feature and the controls work well. For the price it is an excellent buy. I would not say this is built like a tank but, for me, I am very careful with my equipment so it is not an issue for me. It does the job well and has enough bells and whistles that I feel like I got more than my money's worth. The slide controls are advertised as never needing attention or lubricating which is reassuring. They seem to operate smoothly and work well for the job they are designed for.
