I have been modeling for over 20 years I have been modeling for over 20 years, mostly involved with model train layouts. There are no words in the dictionary that would accurately describe your puzzles. I am so impressed with your product. I find myself unable to pull away from my workstation. I am currently building the train and passenger car puzzle. Your materials and instructions are wonderful. I have large numbers of people involved with my train layout and they will “all” be exposed to your product. Very impressive.

Galaxy Marble Run - not worth the money or trouble Galaxy Marble Run - caveat emptor! - - this is a shrew to put together, key parts break easily and the gear mechanism that runs the largest section is inadequate to the task. Customer service is 'bots' (not real people). They are arrogant about how their product is perfect and if it doesn't work, it's your fault. - - that's NOT customer service. Too much trouble and costs too much - not engineered well and difficult to build.

I received the 3D Spider kit as a…Birthday gift I received the 3D Spider kit as a birthday gift. I was excited to get going on it right away. I have built other kit's in the past. Opening I was surprised to notice that there was not word in English indicating inventory nor was there any instructions.. The You Tube video was just as bad. How many rubber bands are there suppose to be used, and how many are extra. I still do not know how many bands go on the hooks that drive the legs. It is a great product just missing a lot of information.

Very difficult to work with the tooth… Very difficult to work with the tooth picks. Pieces are cut inside other pieces and makes it hard to get them out without breaking. Fit and clearances not very good, needed to sand and trim pieces before they would assemble.

Great concept, sloppy execution I bought the treasure chest to assemble for my daughter's birthday. I have built other wooden models from other companies, and this is the first time I've found anything so infuriating. The execution on the measurements is abysmal. Nothing fits quite as it should, always too tight by a smidge. I get that wood breathes and that it can expand, yet this is what laser cutting is for: precision. Insofar I've broken a couple of pieces simply because they would not slide in their lodging, and I had to force my way through. I'm keeping my hopes that I can eventually get to the end of this, but it's the first and last time I'm buying a product from this company. Ever heard of quality control? No? You should look into it. At 60€, this is unacceptable. So disappointing.
