Not able to keep up with angel speeds and matrixes.
It is much better that a revy, it has a durble shell compared to the new revy's weak plastic shell. Feeds with no problems, sound activated so it will not drain batteries. The sound activation goes off sometimes on accident, but it will not break balls unless you have them tightly packed in.
Excellent buy, you can find them for a good price and you will not have to worry about chopping.
