Addition to review: I wish there was a way to have a default time period for download. I have to set it each time I send a file. There are no settings for a default time that I chose. Their default setting is one week.
*****

This is my first AppSumo that I'm actually thrilled about.
I'm not too tech savvy but it was incredibly easy to set up.
I send large files a few times a week to clients. These are huge files, audio/video.

On Sinosend you can choose the time the file is available for download from a week to up to a year maybe more. But I set mine for a year.

I was able to create a personal link to my website (eek don't ask) with DNS set up etc. Incredibly quick and easy through my namecheap host.

You can send a personalized message or even an audio message for your client, attached to the file you're sending. How awesome is that? I may start doing that. The audio is also very good. I tried it with and without my Yeti to record it, and it sounded amazing even without the Yeti. Nice touch SinoSend!

I'm able to send files super quick and I'll get a nudge when the client downloads. I can see their location and time of download. High5 🙏🏼5️⃣to SinoSend on that one.
I've been using WeTransfer for a number of years till now I have SinoSend.
I'll be switching over.

The only difference is and I know they're working on this, on WeTransfer that's one of the earliest ones of this kind of product I have a large wallpaper with my company's logo on the background. SinoSend is working on this.

I attempted to sign up for Transferchain.io and it was a disaster. I'm going to ask for a refund on that one.

SinoSend with the tech staff Richi the co-founder is incredibly quick. As soon as I signed up and asked for a personalized link he sent me the instructions super quick and it was all set up within a couple of hours.

I really hope this product takes off. The best one AppSumo has offered to date. No glitches, all super easy and smooth to use!

Addition to the review. I forgot the expiration date so I was able to go back into the files already sent, and adjust the expiration date in a super simple way as there is a drop down calendar and you just put in the new date. And it saves automatically.
Simply put, an incredibly well made program. They thought about everything it seems.
