Bests & Worsts Reviews from Amazon

I am one of those Amazon Primers who reads scads of reviews and hems and haws before finally coming to what I hope is the best decision for quality, price, and value. I looked at the sets that are rated highly, have about the same amount of pieces, but cost about $15 more. Several reviews convinced me that the cheaper sets had pieces that fit loosely, didn't offer REAL glass marbles (some do but the bulk of the marbles are cheap, plastic ones), the marbles weren't standard size and therefore you could not buy regular marbles for replacements to fit the tubes, or the set pieces are smaller than expected. For our son's 6th birthday, I wanted to get a set that would last, where the pieces fit together well and securely, offered real marbles that were standard size, and could be built to a desirable height for a boy who has been asking for a "marble track" for months. This set has not disappointed. I feel as though we got the best deal for the amount spent and the quality is quite satisfactory.
