Razor added to their range of Jett rear wheeled roller skates, one with a sparking feature. This is activated when you push the heel down as you are traveling along, leaving a trail of sparks as you go. This happens because at the back they have replaceable spark pads .
Apart from the obvious fire risk this poses when you go over combustible material, they just do not look and feel safe, and make the most irritating screeching sound of any toy imaginable! Though on the company website the product has had a grand total of five reviews in the last two years, all highly favourable.
