I've tried their pump and it was a piece of junk...mind you I have a real 870.
The over under however I purchased two seasons ago and has been great. The break action did need to be opened and closed with a little force at first but works just fine now. As for the price, this is one of the best post purchase feelings I've had from buying a gun. This is definitely a good shotgun to buy for someone who wants to shoot skeet a couple times a year and doesn't want to do it with a pump or with an expensive O/U.
