On your site in the top right corner was a link to your store and a description of pretty much all your Sensors, Controller, Mechanical Parts and most everything else. I know your store is being handled by Amazon and a few other vendors, I liked buying from Makeblock direct best, I could order anything, not so on Amazon.
Please put back the link to the description of Sensors, Controllers, Mechanical parts and all the rest. It was a great resource. If I’m not mistaken you also had links to product data sheets etc. Please also include part numbers and where else you can buy the item, since only a small part of your inventory is on Amazon.
