I have a love/hate relationships with acts like This.
An act like this can be very entertaining and commercial, however I myself would never want to do something this reliant on sound effects timing. If just one things gets off you are screwed and it gives you VERY little room for improv or having fun with the audience. It's almost like you are performing at them and not for them.
The plus side is you look very polished and practiced, but if you go too far certain moments can come off as fake and forced. It's a fine line you must walk if you plan to do an act like this.
