Not so long ago became the owner of a PC after the console. Accordingly, I initially tried to connect a PlayStation 4 gamepad via Bluetooth 2.0 so that after displaying the image on the TV, I could play like in the old fashioned way sitting on the couch but with better quality)). Connection through programs, dancing with a tambourine, constant dumps, high signal delay. I decided to buy a gamepad from Series X (I thought it was a matter of dual shock). Unfortunately, the old adapter did not work with the new gamepad. I decided to buy a Bluetooth 4.0 adapter. Everything worked, but in the case of a joint game, the gamepads from Sony and Microsoft seemed to intersect, which caused interference on both devices. Then it was decided to take this adapter and WOW! Everything worked, no delays, no dumps, it connects in a second like with a console! In general, if you don’t want to dance with a tambourine and play comfortably, then this item is necessary for purchase)
