The burr and bolts are all made in Canada. Quality of construction, fit and finish are very good. The burr is about 6.5cm all round, solid steel and zinc plated while the trick bolts are between 3.5cm to 4cm and finished with a very nice matt gray.
I struggled with the burr for quite some time. Although only six pieces, the burr is pretty challenging, partly because its difficult to try to handle several heavy pieces all at the same time; but mainly because I am pretty lousy with burrs. I used my Charles Perry Ball as a guide but comparing both, the Lee Valley Burr has a different design to its pieces. This made the Lee Valley Burr much more difficult to assemble. Eventually I gave up and checked the solution offered on their website. Without the solution, I would have taken a good while longer to solve.
On the other hand, the pair of trick bolts were pretty easy to figure out. Solved both within seconds, and that's because I have played with other trick bolts with similar mechanisms. The bolts are well constructed, so no chance of any moving parts getting stuck, unlike some other poorer quality ones.
All three puzzles came at a very reasonable price making them excellent value for money. If you do not own a trick bolt, and not sure whether to plonk down the dough for the Rolls Royce of trick bolts; ie one of Rocky Chiaro's, well, here is a chance to own a pair of high quality ones at a very affordable price.
