Monster Truck kit
Arrived a day earlier than expected, very well packed. I have made two kits from Ugears and this is similar but more complicated. To date have managed to assemble the gearbox for the drive mechanism. Great fun and cleverly designed. Find I must wax every gearwheel and bearing to ensure the mechanism will turn. But then it does work. I would have thought it a bit too complicated for a 14 year old unless really committed to modelling. It needs time and patience and I find it a challenge and relaxing. Would thoroughly recommend.

Absolutely hooked
Having put one of the cars together as my first attempt at these superb models and enjoying every minute, I went for the Bigboy truck. The more time I spend building this, the more I realise what a fantastic product it is. The thought that has gone into these is amazing. This one would be a difficult first go, but once you work out the instructions, and what the symbols mean, they are easy to follow. I am half way towards building the Bigboy truck and still enthralled with it. Shut myself in the shed, with the radio on and a cup of coffee, and I lose track of time. Some of the parts take some persuading to come out of the cut-outs and it's no good using brute force as breaking one of the pieces would cause problems. Everything fits together superbly, and it's great when you start to see it shaping up. I love them, and going to spend a fortune on them in the future, but they are worth every penny.

Tad expensive, but compliments the truck and both look good together.
Lots of little bits, some very thin flexible pieces which felt might snap whilst fitting together. On the whole not the most challenging to assemble,a little expensive but looks good when attached to the truck.

It looks amazing when finished but...
This is not an easy model to make. It is often very frustrating. You have to deal with a lot of internal mechanisms, which may not be ideal for a casual model maker. I have been making models for 20+ years so not a beginner. Pieces are held together with wooden cocktails sticks. The tightness means that its often very difficult to slot the sticks into the available holes. I spent most of my time shaving down the sticks with a sharp knife. You also need to use elastic bands to wind up and power the moving parts. The pieces are easy to break. I am not a clumsy person, actually very careful - but I broke 5 pieces in total, luckily they were non essential internal parts so they didn't show. I worked on this for a full month (a few hours every day) so you need patience to do it. Once it starts taking shape, you do start to feel satisfied. So its fabulous looking when its all over, just be sure you want to put yourself through the ordeal.

Good model
Good to make & looks good when made up alongside the truck

Terrible model to make.
I have only given this model 3 stars because I'm comparing it to ROKA models which I normally build and I thought I would try a different maker. Big mistake, firstly the instructions compared with ROKA are rubbish, the ease of taking the pieces from the main sheet is terrible, the fact that they provide cocktail sticks that you have to cut to length, and rubber bands which also have to be tied to make a certain size, is cheap and nasty, fitting the parts together, a child would have no chance as an adult with vast model making knowledge, I struggled sometimes. I have been working on the model for 12hrs and am only half way through the instruction manual, so how anyone can do it in the 8-9 hrs stated I would like to see what the finished model looks like and how they did it in that time. I will definitely not be buying any UGEARS models in the future, I will stick to a make that I know will provide a quality model with clear instructions and a joy to make.

Keep on trucking !
These models by Ugears are the most refreshing new range of models to come on the market in recent years . They are NOT for beginners , especially if you want them to perform as promised . They will teach you patience , carefulness , and tenacity , but if you keep trying , they will reward you greatly . Absolutely superb in every respect .

Es genial. Pero hay que ir con mucho cuidado a la hora de montarlo, no podemos olvidarnos que es contrachapado y por tanto endeble en algunas piezas. A mi realmente me ha entretenido mucho. Compraré mas productos de esta firma.

Som vanligt är det svårt att få mekaniken att fungera, en liten ställning ska kunna vridas ut med brev MEN Nej det lyckades inte.
