Yes I have, it's a decentralized exchange and one of such trying to remain relevant. However I think with proper improvement and upgrades they can offer more; this is because I have used the exchange and during my first time of withdrawal it took time I had to complain on their Discord group but ever since then haven't experienced such. People don't like any form of delay both in depositing and withdrawal, so if they can offer faster withdrawal and more good UI, they will do well.
