Seller's android box is the best! No lag. No ads. Very smooth. So many channels. Apps are good and really no advertisements at all. I bought a few boxes from other sellers before (box laggy and full of ads) and they cost as high as $339 but this seller only sells at $98 so I was abit skeptical at first. I thought why so cheap. I bit the bullet and went ahead with the purchase anyway. I'm glad I did. Seller is very knowledgeable and helpful. Will purchase more soon! - a very happy customer.
