Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
