Samsung フリースタイルポータブルLEDプロジェクターバッテリーベース、USB接続、ホワイト。

It's been years and it still works great. Easy to set up. PortableThe freestyle itself has a beautifyl clear display, excellent brightness and awesome bluetooth connectivity.

Worst product

I can use my freestyle without power, however, it's a bit hard to attach it. Great benefits, with this external power I can watch a movie for about 3 hours and I can use a massive charger.

Has held up so far. The first one did not do well. Samsung disappointed me with the first purchase. Get the protection plan. I normally don’t, but I recommend you get it with this one.

Do not buy this! It won't hold a charge for more than 30 minutes. And, unfortunately, we cannot return it since we're past the (very very short) return window. Maybe the one we have is defective, maybe not. Regardless, its not worth $1.89 let alone $189. UPDATE: I have been working with Samsung for 14 weeks to get a refund. I sent the defective battery back to them, which they acknowledged. Then weeks went by before I could get any response to my repeated inquiries. They said that the battery was lost in their warehouse and asked me whether I wanted a refund or a replacement. I asked for a refund. They offered me $129 (I paid $187). They said they needed the receipt. I had already sent it; but, I sent it again as they requested. Again, weeks went by without response to my repeated inquiries. Yesterday, a new battery arrived. I didn't want a new battery as I had told them and as they agreed to. The entire exchange felt a bit dirty and dishonest. I've sent more communications asking for a refund. But, I suspect they will continue to go unanswered. Listen to the negative reviews. You may get a working battery or you may not. If you don't, you sure won't get your money back and you will spend months trying.
