Question: We were very disappointed with this product and plan to return it. Neither of us is a train hobbyist; we purchased this to put on a table top around a small Christmas tree. Parts were broken, misaligned, and did not easily 'push' together. The notes below detail these issues. 1. One of the linkage bars on the train engine was not attached to the main drive wheel and just flopped around. Since the bar wasn't necessary I decided to tape it to the side of the engine and see how the train operated. 2. The coupler height between the coal tender and the passenger cars was mismatched to the point that the car would become disconnected whenever the train would go into a curve. I tried each car but they were all the same. 3. The track didn't just 'snap' together. It was necessary to slightly wiggle and twist the track when pushing it together so the small metal clips engaged with the metal part of the track. In several cased I had to use the tip of a knife to lift the metal clip up into place while pushing everything together.

Answer: negative


Question: They look just like the product photos and I absolutely love them. They're really cute and they're now my travel toothbrushes because they stand up. The bristles are sturdy and a good hardness for toothbrushing. My teeth feel clean after using them, but my gums aren't damaged from overly hard bristles. I imagine they'd be great for little kids: to convince them that it's fun to brush one's teeth!

positive
