Avis clients de grand-illusions.com
Maxwell's precessing top very interesting and instructive, and Tim's demonstration piques one's curiosity. I have found it difficult to get the top to move through as many cycles as Tim's shows; perhaps one third as many is the best I have yet achieved. Moreover, unlike his silent top, mine makes rather a grinding noise in operation. I have tried to alleviate this with light application of oil, but this did not improve matters. Any tips or additional advice from the experts welcome!

Hi - Page 11 of the instructions shows how the pointed end at the bottom of the spindle should rest in the dimple in the base (or journal as it is called). If the top is not spinning for long as it should, and is also making a noise, this is probably where the problem lies. I find it is sometimes helpful to hold the whole top upside down in order to make sure that the brass top is properly seated in the dimple.
Please can you let me know how you get on.

I would suggest you better coordinate the information in your shop. I never received the item and, as far as I know, it has not been shipped yet.
Best.

I am very sorry about the delay. There was an unexpected last minute problem with the anodising. We have now received the new shipment of the Maxwell spinning tops, and your order will be despatched in the next day or two.

My order came surprisingly fast. And the assembly instructions were clear and easy.

The delivery to the Netherlands was fast, in just 3 days.
The product is up to expectations and the handling, customs and delivery by DHL went well.
So despite the maybe higher costs due to brexit etc, I'll stick to grand-illusions whenever they have the product I am looking for. Their communication and fast response are great.
Thank you.

Delivered very quickly in two days well packaged and protected. The items are all great I did notice of the two fire steels I ordered one came with a steel ruler/tool thing and the other didn't-there wasn't one shown in the picture of the item to order so am a bit perplexed as they were both sealed packages, I'm not complaining as I wasn't expecting it, but it's a bit of a mystery!

Hi - so pleased you liked the flying machines. They were a bit of a find, tucked away in a forgotten corner of a warehouse!

Arrived in good time and worked really well. My students loved it.

Fun pen and works as described
However, the fire steel I also ordered was not really worth buying. We didn't succeed in making a fire with this one, even if the person I gave it to is experienced in the matter. There were some sparks, but the steel didn't stick to the wooden wheel and the process of making sparks was more tedious than with another fire steel my friend already has.

A great shopping experience.
Kerrie A. le 22/7/2023 à 04h54
The products are awesome, so GrandIllusions.com deserves a 5/5. My problem is the shipping company they deal with: DHL is the worst company for Canadian buyers who buy from a foreign country because they systematically charge duty & import taxes and they do so at a shameful rate, something like 30% of the price paid for the items. It almost spoiled the pleasure of getting my package.

Very speedy delivery, excellent merchandise and customer service.
Michael B. le 5/7/2023 à 12h48
I love the product. Very good quality, very satisfying. I play with it all the time. I love mathematical illusions. It’s art and mathematics.
If you are in EU, be careful, ask the seller not to use DHL. This carrier ask a huge fee to take care of customs. What you buy may be doubled. The minimum fee for DHL is 6 times the one asked by the Post.
