Brilliant
It's very nice make, you have lots of extra parts just in case, just instructions is a small print, but I use a magnifier glass sometimes.Overall brilliant.Very happy

Kit complete.
Great when built but instructions are printed far too small which meant I had to use magnifying specs to be able to read. Great kit when fully assembled and not a bad price. JUST MAKE THE INSTRUCTIONS VISIBLE.

Returned item - poor presentation and instructions
Bought as a gift. Item is not boxed and comes in a clear wrap so not a suitable presentation for a gift. Instructions visible and so small they're impossible to read! Looking back at reviews this is mentioned time and again. I have returned this item.

Very fiddly to assemble and the instructions are next to useless
Package arrived promptly. Instructions are in several languages but in tiny font. I scanned the page in to my laptop as PDF file so I could enlarge it. The parts mainly go together well but some are fiddly and others needed sanding down to fit (sandpaper included). The whole system needed some adjusting to make the balls run smoothly but great fun when it works. Grandson aged 10 would have struggled without my help.

Wow. The instructions are part of the puzzle I think.
Should be labled 'How to keep an idiot quiet for a week' given as a gift and working well.
