First off first, used Telestream's Screenflow for screen capture and editing and the product is good and easy to use.
The review is about the company's unethical sales tactics. They give the impression you're paying a one-off fee for the product only to realize it is a temporary license.
Why? Because of their forced and paid product updates. They would lock you out of the product in about a year unless you pay for the latest release. The older one would just stop working on your machine, this is if you upgrade your OS. And even if you don't after a while, they phase out support and you will realize certain features will stop working and they will force you to update to a newer one.
To keep using the product, you will need to buy a later version "at a discount".
The initial sales page mentions nothing about this. To be fair, maybe T&Cs have a fine print somewhere. Haven't dug. Then, their support will respond something along the lines of "sorry but it's our way or the highway" and "we're sorry if this wasn't apparent in our initial sales documentation".
No, it wasn't.
Anyone convince me of the contrary by looking at their sales page and I would be willing to update this review.
I urge the company to change their sales page to reflect the fact that new buyers are paying for this version only which will stop working properly unless buyers purchse a paid upgrade or they NEVER upgrade their OS ever.
