I ordered this product because the price is very interesting (74,95) via Japan: Japan Global Shopping Store. On my recorder of the same brand, the Panasonic DMR-BWT735, blank blu-ray work very well. And 20-BD-RE DL discs for that price, it's the best I could find now! By cons, since it comes from Japan, one must take into account the delivery time between two and three weeks (19 days for me). The seller says from the outset the various stages to delivery and reply to emails. Very seriously. I would also recommend this seller !!
