Great, trouble-free service
I've used Wise for a couple of years now. As someone who has lived in a few different countries the past few years, it has really saved me a lot of money by transferring money with Wise. My own bank fees were always relatively high, but especially the FX rate at my current bank was generally inflated compared to Wise when transferring money. Aside from the savings, I've never encountered any issues and the app functions very smoothly. The debit card also is really useful when abroad. 

Overall, I highly recommend Wise for anyone who moves cross-borders a lot, goes on holidays abroad, or has family/friends abroad.
