The color changes a bit from the traditional blue / orange. It is of reasonable size (neither big nor too riquiqui) and it can take two cartridges at a time.
The price is reasonable for the quality.
Warning: only 2 cartridges are included, think to buy refills simultaneously.
Note for those unfamiliar nerve: the cartridges are foam and do not hurt.
With water guns, they are the only guns that I accept in my ;-)
