And they gave us 1 year guarantee. Than they sent us their products. When we recieved here in Turkey their products we saw their all products is fault. And than we told them your products are all fault they told us ''no our products are very quality'' and than they gave me their customers number for referance than l called them for referance from Turkey their customers also told me yes we have also like problem.
