Bought the Windmill 2 months ago and after 8- 10 weeks it finally arrived. Instructions are horrible and almost impossible to discern. almost no written instructions. Many pieces did not fit together... See more

These take up a lot less room than conventional plastic models, therefore I've begun a collection of them.

Order MO19583. This was ordered on 29th November. As others had said no communications to say about a delay. Only today do I get an email to say it is finally being shipped, so will not arrive in time... See more

Bought the Windmill 2 months ago and…

Bought the Windmill 2 months ago and after 8- 10 weeks it finally arrived. Instructions are horrible and almost impossible to discern. almost no written instructions. Many pieces did not fit together . I am in the middle and 2-4 pieces which I believe will be of some importance do not fit ie nuts onto screws. Likely will not order from them again. A big disappointment

Parts for a project were mislabeled

Parts for a project were mislabeled, the company ended up sending me replacement parts but by the time the parts came the project fell apart, the company has gone above and beyond to help me in a time of great need and I appreciate them so much

Delayed but resolved in the end!

My dragonfly was marked as received but it never came. I didn’t get any luck when I first complained in December as it was for a Xmas present so I was gutted. Decided to email again around June as I had paid for it, and I still really wanted it for my partner. It got shipped within days, they were really helpful and I think maybe overwhelmed at Xmas. He’s currently sat doing it, big hands and tiny parts are keeping him and his mind very occupied which is what I wanted - an hour every evening even if it takes a few weeks is still a fun project for him! Well recommended!

Absolute disappointment

Absolute disappointment. Building this model was not enjoyable at all and mostly felt like tedious fiddling with tiny parts. Many pieces fit poorly, everything ends up looking crooked, and I spent more time correcting issues than actually assembling the model.

What made it even worse is that the instructions do not always match the actual parts. Several steps are unclear or incorrectly illustrated, making the assembly far more complicated and frustrating than it should be.

On top of that, some parts require so much force to fit together that my fingers actually started to hurt. I can hardly imagine assembling this alone – even with two people, some steps were unnecessarily difficult.

For the price, I expected much better quality. For me, it was mostly frustration rather than a fun building experience. I would not buy it again.

Excellent Quality and Lots of Fun!

These kits are the BEST! have purchased 5 kits over the past couple months and I have been very happy! The quality of the metal pieces is excellent. The directions and labeled parts make it easy to follow steps. The kits are challenging in a way that keeps me entertained and busy. I love to spend time on the weekends building the metal kits. It is so satisfying when the pieces come together! I would recommend these kits to anyone who enjoys building and is looking for a fun new hobby! Customer service has always been helpful and friendly as well.

The stars are going up

The stars are going up! Although my initial review showed my frustration, I now consider the timing of my order in November (Christmas rush) may have played a role. When I finally received a response to my inquiry, the replacement parts were sent promptly in March. As noted in my earlier post, my son no longer has the time to build the kit. I’ve passed it on to my daughter so I’m waiting for her to complete the project. Once I get her honest feedback, I’ll update my review for the actual kit. I have been impressed with the recent communication from the company regarding my experience. I am hopeful her experience with the project will be positive as well.

I’ve built 2 models

I’ve built 2 of their models so far, the Hercules beetle and the Nebulipedes and both models were brilliant. Nebulipedes was a bit more challenging but the finished model looks fantastic. The beetle was very straightforward, only 1 screw was a bit too short and it looks amazing on display. Both models have lights as well which look great. I can recommend their assembly kits for sure.

Parts missing and MOSTARLE are no help

Parts missing (knurled nuts for legs) and bag contained oversized threads. It would cost £1 for each one and I need six. Since I have just begun the build I have no confidence there won’t be more. Junk.
Money back required me to return in original unused condition so can’t do that. This company don’t help despite me contacting them. Don’t buy these awful kits.
