Very strong first impression.
After several real-world tests with large video transfers (8 GB, 18 GB, and over 26 GB with hundreds of files), I wanted to leave an honest review of Sinosend.
I normally use professional transfer platforms like FromSmash for video production, event delivery, and client work, so I wasn’t looking for “just another cheap transfer tool.” I needed something capable of handling real production workloads.
What I liked:
* Very stable uploads, even with huge transfers
* Surprisingly good transfer speeds in Europe
* Clean and professional interface
* Excellent branding customization for client deliveries
* Integrated video/audio previews work really well
* Fast downloads with very little friction
* Handles hundreds of files without the interface feeling unstable
* The client experience feels far more premium than I expected from an AppSumo product
One thing I especially appreciated is that the delivery page feels more like a professional studio delivery portal than just “here’s a ZIP file.”
Things to keep in mind:
* Long-term stability still needs to be proven
* Some US-based reviews mention inconsistent speeds depending on the region
* It’s probably not yet at the “enterprise infrastructure” level of long-established platforms like Dropbox or WeTransfer
That said, after real production-style testing, I’m genuinely impressed.
For video creators, editors, agencies, or studios regularly sending large files, Sinosend is absolutely worth testing.
The developer also seems responsive and genuinely invested in the product, which is reassuring for a growing platform.
Very strong first impression.

Edited May 29, 2026This is an incredible review, and coming from a video production pro who regularly moves massive files, it means the world to us. Thank you for putting the platform through its paces!
We've revamped the interface (and continue to do so) after the initial UI complaints last year, and like that the "studio delivery" feel resonates with you. We still have a lot of work to do on Mobile, as moving GB via 4G, LTE isnt so stable in certain developing networks. We realize what needs to be worked on and adding it to our roadmap
To be completely transparent, we didn't actually set out to build a video delivery platform (and I dont think we are) —our core mission is pushing heavy business documents and massive file batches across strict borders. But it turns out that making infrastructure bulletproof for global trade has the awesome side effect of making it fantastic for heavy video pipelines too! (If you ever need raw, ultra-specialized media workflows, MASV is another great tool in the space you should definitely check out, I cant speak to formsmash, as they remove data after 30 days, and that doesnt work for our clients).
To speak to those early speed reviews you mentioned: during our first launch, we only had one APAC region live. We listened to that feedback, and today we have 8 global storage regions and counting (including Europe, US, and mainland China). We believe we might be the first to offer direct Mainland China regions for consumers (not enterprises)
What we're most proud of is our on-demand region switching. Unlike other tools where you pick a region and forget it, Sinosend lets you change your data location per transfer and per request. So if you have a client in the US today and one in Europe tomorrow, you can optimize the speed and compliance for each specific delivery.
We’re fully locked in to proving that long-term stability and keeping this infrastructure rock-solid for your production workloads. Welcome to the club!
Best,
Rishi & Team Sinosend
