This is a good product. You have probably triple the amount of features the stock chip has. All the firing modes are alot of fun to use as well. You can really customize your gun with this thing as far as how it shoots. The only thing that is bad is trying to switch firing modes. You have to press the trigger and on button at the exact same time then you can select different modes. Usually it takes a few tries to get it. The tourny lock is a nice feature and nitro is alot of fun.
I would say get it unless the other chips out there are better.
