Several weeks ago I purchased this item for my 10-year old grand-daughter. The product is imported by Unicorn Enterprises Corp., in Mississauga Ontario. Although the spider is rated as suitable for “age 8+” it probably should be rated for age 12+. Notwithstanding the assembly and instruction manual being quite well written my grand-daughter did experience some frustration putting it together (as did her 12-year old brother AND xx-year old father). So….YY-year old grandfather (that’s me!) to the rescue!! After sanding down a few parts which seemed to still have slight burrs on them….. the spider has come alive…..crawling around contentedly and making the whole family happy!! This “toy” is in my opinion worth the price: not only in teaching the builder how to follow instructions, handle small/delicate pieces carefully, exercise patience etc but also in learning the science behind how clean energy can be (easily) created and put to use. I’d definitely recommend this product, and rate it 9/10.
p.s. Unicorn Enterprises is a delight to interact with - responsive to emails and going that “extra mile” for the customer.
