I would like to recomment this product and the buyer for you guys!!!
I bought it last week, and the product came to me in 4 days, they send to me directly from the warehouse of the US, really fast shipping. I used it, and I love it!!! I use it in the garden, so I need to use the Offline Controller, but at the beginning is really difficult to understand, so I turned to the customer service, they just being so so patient! They taught me step by step, and finally I got it, and make a beautiful laser craft (it's too bad I can't attach a picture here) I will totally recommend you guys to buy it from ortur.net.
