UGEARS Marble Run Chain

The box was a bit damaged, however it looked really good otherwise! Fast delivery as well. Thanks

The marble run works perfectly. There was an incident of a broken part due to the cat sitting on the part, so I had to glue it together, but other than that it was very good. You need to be careful when releasing parts, a good sharp craft knife will do this - DO NOT try to just pop the parts out by hand. Some of the clip together joints are tight (they need to be), so this is quite punishing on your finger and thumb ends...I suggest an hour or two, then leave off for a day. Total assembly is about four to six hours, but you MUST follow the instructions and each step carefully. I was actually well impressed. Not sure I can finance another one (or especially another 3), but I'm intrigued to see how an assembly of four would work. From previous experience, the elastic bands supplied break down in sunlight very quickly, but for this model they're not massively necessary so that's not so much a worry.

This is fantastic fun to build. The 1 and two star reviews are unwarranted in my view. The pieces are sometimes difficult to remove but if you are patient and think about it, they can be removed quite simply. And yes, the pieces are a tight fit (which makes it a robust model). Again patience is required and a diligent use of pliers without excessive force always does the trick. This particular run actually has four separate tracks which the marbles determine themselves and then it resets itself every fourth marble. Quite brilliant. Complaints about the chain are nonsense. As long as you sandpaper the chain parts before assembly to remove burrs and, once assembled, rub on the supplied wax - no problem. Mine runs as smooth as anything. All complaints regarding this model are due solely to the impatience of the reviewer (in my opinion).

I bought this in lockdown to pass some time, a bit sceptical of the price, and it provided a lot of entertainment value. You must be careful to not break the pieces whilst removing them from the wooden cut-out (they do give a useful tool to help with this), but it is advertised that they send out spare pieces if you require them. I never requested spares though The instructions are manageable to read - some arrows pointing to places on the model are a bit vague. Be careful- some parts of the assembly are quite fiddly and can cause pain in fingers After a while, the marble run stopped working as it should but I was able to fix with some blue tack structural support. Overall, this was a good purchase and well worth the money. I ended up buying another one in the set to connect the two.

I bought a pair of these so that I could link them as advertised. This linkage works very well, but is the only flimsy element, and care is need in moving the complete assembly. Otherwise I have nothing but praise for this complex and ingenious construction. It's certainly very complex, and therefore not at all suitable for a beginner in this type of thing, but as long as you take care in sanding down the odd break-off point where a piece is detached from its framework, and use plenty of candlewax (supplied) to grease the moving parts, it goes togther very well indeed. The intructions are very clear indeed, and highly commendable, and the accuracy of the design is awesome. . Best of all, it comes from the Ukraine, and therefore buying it will help to support their industry and their economy - I hope that both survive the attempt to destroy them. I've already bought other models in the series and am looking forward to getting stuck in.

I have to commend Ugears on the design and execution of this exquisite model. I’m a 72 year-old child and long term Lego Technics builder and find the design of these wooden models as exciting, if not more exciting than Lego. While Lego is constrained by a finite number of manufactured pieces, with laser-cut ply, there are no such restrictions. Any part or shape the designer needs can easily be manufactured. I have previously built several very complex models from Ugears (and others) with varying levels of success, satisfaction and frustration. I can say, without reservation, that this is the most satisfying and ultimately playable model I have built. I’ve ordered the other “linkable” marble run model as a Christmas present (the Step Hoist) so I’m looking forward to building, linking and playing with the combined results during the cold winter days to come.

This is my third Marble run from UGears and the worst. Due to its construction it makes it hard to turn the handle as on doing it the whole frame moves jamming the gears each turn making it unplayable. Also even if you struggle to do it or turn it by hand the marble run is very disappointing. I would like to add that the other two Runs I have are perfect and would highly recommend them

Ugears get better and better. Superb accuracy of parts- an engineering marvel. A satisfying level of complexity if you like the 3D modelling side. I like the way that Ugears uses slightly different thicknesses of ply so that there is strength where needed. A couple of minor points- a couple of the guidance pictures are tricky to follow- but that is the 3D challenge. You have to 'adjust' the physics of the mechanism a bit to keep the model working consistently but that is problem solving. The wax is essential to keep the mechanisms smooth- an extra stick of wax would help- don't use candle wax as it is too 'sticky'. The wax provided is very soft. All in all highly recommended.

Résultat fidèle à la photo. Amuse les petits comme les grands. Attention,. certains pièces sont difficiles et fragiles à sortir de la planche, il y a un risque de casse. Il faut être minutieux mais le résultat est top.

小4の子供ではパーツのはめ込みが硬くてできない箇所もあったが、それぐらい硬くないと外れやすいと思う。はめ込み時に蝋を塗るとはまりやすい。作る過程も楽しいが、完成後にマーブルが流れるのをずっと見ていて飽きない。小さいパーツは予備が予め付いていたり、もし紛失しても無料で送ってくれるる気遣いが嬉しい。Ugearはウクライナ発なので、ちょっとだけウクライナ支援をした気分も味わえる。

sicuramente bello da vedere, molto delicato nel montaggio ,consiglio se sei stanco smetti, alcuni pezzi molto fragili alla fine soddisfazione al massimo.

It was too challenging for me. The product looks great but it was more complicated than I wanted to handle.

Il lavoro di montaggio deve essere meticoloso: gli incastri sono perfetti ma bisogna prestare molta attenzione e agire con molta calma. Il risultato è ottimo! Gli ingranaggi girano bene ed è diventato il passatempo preferito per i miei nipotini. Penso che acquisterò gli altri tre da montare assieme.
