SpaceRail Glow in The Dark 6,500mm Rail, Roller Coaster Building Set, Marble Roller Coaster Kit with Steel Balls, Great Educational Toy for Boys and Girls, Level 1.2

The parts on this item are very small, some around 1cm. It took my husband, who contracts and builds engineers plans for a profession three hours just to get one of the tracks together on this dual track item. The second track was never able to be attached, and if you moved the item in the slightest manner, all the calibrations get off and the whole thing has to be readjusted. The balls often get stuck and simply fall off. After six hours, this item went directly into the trash. Our recommendation would be to simply not waste time or money on this purchase. I would have returned it, but when my husband threw it in the trash I was not about to dig 1cm pieces from the trash to attempt a return, not to mention he had to cut the 1st track to even get it to occasionally work.

The idea of this is really cool, what is absolutely not cool, is the rails aren't cut, zero parts are labeled. And the instructions look like pictures with crayon lines. Zero reference points as indicated in poorly written, and conveyed instructions, which is written in Chinese, and poorly subtitled in English. Would be a with while investment to have an english only version. With clearly labeled parts.Word of advice, look where the main parts go, with orientation, and cut the rails to fit as needed to connect, using a piece of coiled rails and having to cut a straight length per the cut chart is an utter pain. And will leave you short, and short tempered.If you aren't inclined to build things, buy Legos, if you are.. this is pretty cool. But take the lengths and cut measurements as well as the poorly written instructions with a grain of salt.

About the only thing this "coaster" is good for, is learning how marble machines are designed and work! It is NOT as shown. The dimensions are WAY off. It's not as high as specified, which causes problems with the balls returning to the elevator on one of the runs. Selfon redesigned the long run to make it longer which is also part of the problem! It CANNOT be made or adjusted enough to get a complete run of the long rails. It ALWAYS stops short of the elevator!! It's designed for a kid, but a kid would get discouraged long before I did to get it adjusted properly for complete runs. Not recommended except as noted above, as a learning tool!!

Grandson just 7 loves this. Took his Dad awhile to put together, but my grandson and his 11 year old sister loves it! Pretty cool.

My nephew loved these. The only problem was that the instructions came in a different language. My husband got a text message saying that it was a great gift but his mom wished that it were in English.

The instructions are poorly-translated English, so it's a bit tough to read in general, and the instructions are tough to figure out. It's a good introduction to SpaceRail, although you shouldn't expect to just hand this to a kid and have them figure it out. If you can work with them on it it'd be a good thing to build. Patience is the name of the game.

Love spacerail, got this for my daughter and I. A bit hard to get everything adjusted just right to keep the ball on track once assembled,but we'll Worth the time and effort!! Would highly recommend to anyone who likes these types of things, quite educational. Great product!

It's nice that it glows in the dark and it connects nicely. What I dont like is the instructions are in Chinese. So were putting it together our own way.

作り方は英語＆中国語でしたが、親がサポートすることでワイヤー以外の組み立ては年長息子でもできました。ただ、ワイヤーが固いので年長息子では切れず、適切な長さに切るところは親の出番でした。また思いのほか玉がスムーズに流れないです。途中で落ちたり止まったり。レベルが上がるといろんなところでスムーズに流れないであろうから調整が大変だろうなと思います。

説明書が、日本語が、無かったので　中々分からなかったが、慣れると　同じ事の繰り返しなので　説明の図だけでわかりました。ホースは、少し長めにきって後で調節すると、良い。短すぎると　もう使えない！出来上がると　凄く見応えがあり　難しいステージにも　挑戦したくなります。

作るのは簡単でしたが、付属のレールが曲がっているのと少々短かったので、もう少し長いレールが入っていれば、いろいろレイアウトを工夫できて楽しくなるかと思いました。

プラモデルの方が良い。丁寧に作ってみたが構造上ヨレがありあまり美しく無い。

説明書が日本語でなかったのを確認するのを忘れてしまい作業が大変でした。
