This product is worth it. I don't think it's a perfect match for the original battery, but it's good. Works well and lasts a long time but doesn't seem to have the full performance of the original battery. Definitely not a failure, just a little less. The battery compartment is very difficult to access. I was really scared the wires would break when I finally put it in because it's so tight. All in all I don't think I would buy it again. I think when this battery runs out I'll look for another vacuum cleaner to replace the brand/model as the quality of the Shark Freestyle seems to be dropping :( I've already thought about replacing the batter or just only the vacuum cleaner itself has not yet bought this battery.
