Pretty happy with the product. Nice beefy with plenty of spare parts. Can't wait to fire it up. Pleasantly surprised
A great buy for kids to learn. Very pleased. Purchased it for a birthday gift. Quality looks great. We yet have to try it.
Shipping was fast, works great. Exactly what I wanted. ( I'm a 55 year old kid with a science fascination)
Works great ,very good build quality with spare parts, already assembled. I took it out the box added a wax candle after 5min I rotated the pulley and it started working
Kids really enjoyed to watch it working
