Do they charge to visit here? Can i findor try all the Samsung good (wearable) here?

No charge. They have all the Samsung tech

No charge and all are welcome to try; there may be a line depending when you go, to use certain products, but it moves fast. You can get products fix and tech support and order items, but no in store purchases.

Yes you can and there is no charge

There is no charge and you can try and play around with the products they have on display. But they don't sell anything.
