I just buy mine from dancesafe
They dont sell Robadope and Mandelin
I dont know of any suppliers in the US - but I will PM you somebody based in the UK who will post you one.
IMHO EZTEST.com is a waste of time, they are overpriced, have horrible aftersales and take too long to process and ship an order.
The company I use and advise are half the price of EZTEST, have a telephone number so you can call them if you have a problem.
Got mine to the east cost of the US in 4 business days. I dont think its over priced i looked around, i dont get why everyone hates on them. Maybe i just got lucky but it seems like everyone tries to push dancesafe on here. I got my ez test in under a week and it was affordable works great.
