The Super Soaker XP 15 is the smallest XP-class soaker manufactured. Roughly on par in size with the Super Soaker SS 10, the XP 15 is a pocket-sized soaker with respectable power given its size. The model tested here comes second hand and was left in a garage, unused for a few years. As such, while it still works, it is unknown whether a new XP 15 would behave quite as this one does.
:: Nozzle
Small soaker size can only understandably power a small nozzle. The XP 15's nozzle is similar in size as the original Super Soaker SS 50's nozzle. Streams produced from the nozzle are small, but good for a soaker this size. Range of the stream is not very far, but this soaker is better used for small fights and/or sneak attacks indoors and out.
:: Pressurized Reservoir
The XP 15's pressure chamber/reservoir holds a small, but adequate amount of water given the overall blaster's size. The reservoir's cap is positioned at the rear of the blaster; its opening is slightly tapered inside. The main drawback to the reservoir's design was the choice of using an opaque plastic; as such, one cannot easily determine how much water is remaining, especially since this blaster weighs so little to begin with.
:: Pump
The XP 15's pump is mounted in the trigger handle. This particular XP 15 was rather difficult to pump well, though it is believed that most pumps would glide more smoothly. The pump grip, however, is rather awkward to hold, making this stiff pump even harder to pump well.
:: Overall
All in all , the Super Soaker XP 15 is a nice little soaker. While definitely not meant for large water fights, it still holds the title for the smallest XP-class soaker, just a touch smaller in size than the chubby Super Soaker XP 215.
Pros
Small, easy to conceal, decent stream range for its size. Reservoir holds a respectable amount of water considering the overall size of the blaster.
Cons
Pressurized reservoir opaque, thus amount of water remaining difficult to measure. The water blaster tested had a rather stiff pump. Pump grip region small and awkward to use.
