Guess I'm your first customer. 
Tried swapping 0.02 ETH to BTC. Output was 0.0004991 BTC
At the time, ETH/BTC at Binance was giving me 0.00050389 BTC (counting the 0.1% trading fee) for the same amount, so around 0.95% less than Binance.
Transaction was super fast, I think it took less than 2 minutes from ETH sent to BTC received.
The only thing I missed was a QR code for the deposit address on the swap page.
