10088 V8 Engine Model Kit - 535 Pcs to Build Your Own Mini Engine that Works, DIY STEM Mechanic Engineering Construction Set, Hobby Building Blocks Kit for Adults

Got as a Gift for my boyfriend's and he loved it! Pretty good instructions compared to some other builder kits we've gotten before

Takes more batteries then expected but works in forward and reverse. Was bigger then i thought it would be as well.

This snap together kit was fun to do. The pieces are well made and fit securely. The 6 or 7 bags of pieces are numbered, but I could not correlate the bag numbers to the instructions, so I dumped each bag into separate plates. You must look very carefully at the illustrations (I used a magnifying glass) to make sure you are selecting the correct piece as many look similar. The pieces are not labeled (stamped with a number), and the instructions don't indicate which bag to find the piece in - indeed the same type of piece may have 30 in total but be spread out over more than one bag. The engine ran once the kit was completed, so I achieved success, but it would have been much more satisfying having more detailed instructions - maybe that is asking too much for a company that sells these kits worldwide.

My son loves this. It works and is so cool.

Great model, purchased as a present for a brother but one of the crankshafts is missing a piece so I cannot finish putting it together. Trying to figure out how to get a replacement part.

Took a bit to put together but was fun in doing so and interesting, also the parts move like a working engine.

I bought this as a birthday present for my son. He immediately put it together, but whenever he tried to run it, it fell apart. I was going to return it, but I just missed the return window.

I was great to build but parts were alittle loose.

Very satisfying. Parts are made very well, smooth, no sharp edges, fit very very well and snuggly into each other at the designated slots. Expensive. But qlty is commensurate. No missing parts. Instruction booklet was great with good pictures . I made a few silly mistakes in assembling but soon was able to see the pictures and rectify.

Really relaxing, fun model to build. The pieces are made with decent tolerance and great clutch compared to the Lego standard. I would buy this brand again.

Bought it as a present. Had to use some common sense to find all the pieces in the different baggies.... but all the pieces are there! Even a couple of extra. Comes with picture instructions, and took us 1 day to finish. Had to adjust some pieces and tighten the chains, but IT WORKS!!! Very cool!

Purchase for my teens boy as an alternative to legos. Instruction made ease of assembly requiring no assistance from me. Great gift for teens who wish to partake in mechanical engineering.
