Dave Hunter from GuitarPlayer has done a detailed review of the Donner ARENA2000 from appearance, features, controls, performance, and sound. 

Dave says: 

"One of the things that impressed me upon unboxing the Arena 2000 was the general robustness of its construction.  Given the limited size of the unit’s back panel, Donner has squeezed in an impressive bundle of connectivity options. Amp-wise, the Arena 2000 is packed with a familiar list of vintage classics and popular boutique models. Arena 2000 is a ton of fun and an impressively versatile entry-level amp and effects pedal. "
