Things I liked: Weight, accuracy, slide-lock (just for effect only), the look and feel of the gun, very nice. The weight is mostly in the mag, but even with the mag out, it still is heavier than most guns in this price range. The accuracy is perfect, within 20 feet using .20 gram bb's, you can hit cans all day long, you will get flyer's to, that is just normal, long range is good to for a spring pistol (80 to 100 feet), on a non windy day you can hit a big target (tree) often with .20 gram bb's. This gun has no rattles at all, solidly built, and more power than I expected to.
Things I would have changed: For a little more money, add the slide-lock feature to let you know when your out of ammo, you need to keep count of the shots with this gun.
What others should know: If you don't mind keeping track of the shots you take (15), this is a steal at the current price, it has looks, weight, accuracy (out to 80 feet or so with .20 gram bb's) and nice power. It does have the hop-up feature, I didn't see much in the way of using it at the high or low postion.
