Very tiny parts hard to attach the wings and legs 🦵

Customer video review of Terminator M – 3D Metal Model

My first Mostarle model. Beautiful, a lot of fun to put together. My only criticism is the cable which is welded into the lamp. It's way WAY too long, making the model inconvenient to place anywhere. Other than that, I really like this model.

Customer video review of Nebula Astronaut

Adorable little model, I really like how it glows. I had one issue though: Piece B7 did not have a hole wide enough, so the dedicated screw (SC2) did not fit trough. I had to widen the hole myself using a drill.

Loved doing it and enjoy looking at it. I like the fact that it is a bit practical with a light

Customer photo review of Cyberpunk Plasma Ball Spider

The Design is very nice, but we had it multiple times now that the labelling on the small packages are either very bad or not excisting. We figured out where the pieces belong, but with labelling it would have been easier.

Super fun to do. Very hard to pose as some of the linkages didn't want to tighten .. Loved doing it - would definitely recommend

It was a good change to build something that has wheels on it. It would be nice to see more of this type of build. I was impressed with the instructions, super easy to follow. The end result looks awesome. Thank you Mostarle

It was a extremely fun puzzle to put together...!

Customer photo review of Cyberpunk Plasma Ball Spider

It's a great concept, but an infuriating build! I needed an extra hand and smaller fingers for many of the nuts/bolts that were used on this spider. The instructions need to be clearer. I wasn't sure how much to tighten parts, and so the legs were loose when I was finished, and other than taking it apart, I no longer had access to tighten the nuts. I bought a black acrylic board and mounted my spider to the board. I used some of the packing foam from the box to make a "stand", and that helped position the spider. Several steps in the instructions would be easier to understand, if the new part going on the build were outlined in the picture. I couldn't see "what went where" in some places. Overall, these are fantastic pieces, but there's definitely room for improvement, mostly regarding the instructions.

Great fun building this. Wish the hips were easier to manipulate and have a stand to assist in getting it to stay standing. The wheels on feet make that difficult.

Purchased this for my hard-to-buy-for Son. He said he liked the design and the challenge of putting it together. Unfortunately it didn’t arrive in time for Christmas but I will make sure to order earlier for this year.

Customer video review of Nebula Astronaut

The pieces are extremely small - just to be forewarned. Directions were good, several steps were a little tricky but overall it was easy enough to follow. I did over tighten 1 screw and it broke, so I had to pinch hit with the leftover pieces… wish there had been an extra of that 1 screw, but there wasn’t, and nobody would be able to tell. It’s fun enough and it’s cool enough, don’t know that I’ll make another one ever, but maybe.

This was awesome to build, definitely some tricky bits but it wouldn’t be fun if it was easy!

Customer photo review of Terminator M

I got the Terminator for my dad, what a great present! It kept him entertained for many, many evenings. We were missing a couple of parts - they are so small, it's very likely they were in the pack and lost our end, but the customer service could not be more helpful and polite and sent the extra bits straight away. A truely great gift.

Customer photo review of Terminator M

I bought this for my son for Christmas. I had all the fears like everyone else as I too received no freight info and no communication. Eventually I made contact via the Instagram page and a lovely guy assisted me. The item arrived. All bits accounted for and today my son finished it He said it was very fiddly and he needed to concentrate. He loves the end result. He's 38 with 3 kids that love it too. Colour is really nice

Customer photo review of Electric Screwdriver Set

Bought this to help with doing my models as I have arthritis which sometimes makes it difficult. The different bits that come with it are brilliant and makes the process so much easier especially as they are magnetic. Would not be without it now. Thankyou

Customer photo review of Reindeer Snowmobile

This was a fun little build, with a cool design. I have to say that the instructions were good with the simple building of only a few pieces, with the pictures quite large, but when it came to assembling more complex pieces the pictures were far to small and dark to follow. Please supply us with larger more clear pictures. Thank you Mostarle.

I brought this for my husband as a Christmas present, he loves Lego so I wasn’t sure if he’d take to a different kind of construction kit … he’s now on his 3rd kit! He absolutely loves it They’re really detailed models and well presented in the box

Customer photo review of Terminator M

Was enjoyable to put together. Though, it was missing some parts so I had to wait for the missing parts to ship and arrive to assemble it. Support team was quick to fix the issue, so was pleased about that.

Although I had 3 parts missing ( all the same part number ) I was able to fabricate the parts. I had fun building the terminator and the finished item looks great.

Customer photo review of Terminator M

This little Terminator was great fun to build during the Christmas holidays. Some parts are quite small so good eyesight or glasses and plenty of light really help! But it went together really nicely and the attention to detail in the design is amazing. Now it's finished, it looks super-cool on my desk where it also acts as night light.

Customer photo review of Terminator M

The pieces are small with lots of them but a great challenge. Finished product looks great. Did need to do a couple of tweeks with the legs so they weren't floppy.

Customer photo review of Terminator M

The Terminator M is very well made. It takes a good amount of patience, because the pieces are truly tiny (almost like building a watch!). Luckily there are a few spare parts; I needed them because one screw snapped while I was tightening it. I added a couple of washers at the knees, because otherwise it had trouble standing upright. All in all, it was a great experience, and the finished model looks amazing!

Customer photo review of Cyberpunk Plasma Ball Spider

Fue una experiencia muy satisfactoria, desde el unboxing, el armado y finalmente el encender, es un rompecabezas muy hermoso, algunas partes del instructivo no me quedaron claras pero si logre armarlo, por otro lado, la lampara de plasma la encuentro mas que hermosa! Ojala el cable hubiera sido entrada USB c de ambos lados por si se daña el cable, pero de igual forma magnifica lampara, me encanto la experiencia y el resultado.
