Sinosend works great, its very simple to use and does what it should, reliably, with nice additions of tagging files which helps with organizing.
The only thing i dont really like is:
1) Loading times for shared links - its not terrible or super bad, but it is slow compared to other services, when a user lands on your shared links to download theres a loading animation before the page loads and it takes a bit too long in my personal opinion, although its for sure not a deal breaker, but it is something i hope will be improved in the future

1) The UI - it feels a bit dated and bland in my opinion, looking at other services such as wetransfer, their UI feels more polished and modernized with a more premium touch in terms of animations/color scheme/ UI layout and overall feel, i hope this improves in the future, both on the client side for downloading pages and the dashboard itself, but its low priority

Overall I definnitely recommend Sinosend, its been reliable and trustworthy so far,
Best of luck to Rishi and the team building!
