It disconnects sometimes for no reason bro but overall it is nice controller.
Alright, well it would still be worth paying the extra £4 for the wireless adapter. If you don't want it, CeX will give you £7 cash, £11 voucher, or you're likely to get at least £10-15 on eBay. Could mean the controller only costs you £30.
Regarding wireless vs Bluetooth, here's my opinion: The latency for Bluetooth peripherals is not good enough for gaming. It can be bearable in a slow paced game, but even navigating through menus etc. you can feel the delay in input. For me, this is true even for the latest Bluetooth specs/aptx technology. Wireless is a different beast and can obviously mean different things. However, a good wireless peripheral can be literally as quick as a wired one. See the best gaming mice (e.g. Logitech G Pro) which have a claimed 1ms delay. Personally I use a wireless headset, mouse and controller and love them all (like to eliminate wires) for gaming. I have Bluetooth earphones that I would never consider for gaming due to the level of delay, but I otherwise love (as videos automatically adjust to sync the audio on a decent pair of BT earphones).
@pc5020 does the OK Google Functionality work too with this?
