after instaling - you have to pay , if you want download mp3

Bad! Only after installing you get to know that you have to pay for the features described.

Useless. It said I needed to buy pro the first time I tried to use it.

There is no indication until after download that you have to pay for the features described. They give a flimsy excuse for forcing you to buy "pro" in order to download an mp3. Forced "donations" are not donations. This should be removed for false advertising and requiring you to pay to use it.

You have to pay, or does not wrok !
Ne radi !

J'ai payé la version pro, mais rien ne marche, car c'est toujours bloqué par Google.

donate only for dowloand. Не качается 720р и мп3 без доната, проходите мимо

does not work at all; this should be removed

не работает

Started very well, most impressive.
However, after a few downloads it stopped downloading HD formats, restricting further downloads to 360p.
Message appeared saying HD capability can be reinstated upon payment.
Essentially, the software is a try-before-you-buy, otherwise known (many years ago) as "crippleware".

Doesn't download mp3 audio.

GARBAGE - would give 1 star if I could - paid for "PRO" version -- didn't work due to dev site blocked by youtube -- AND had to open a claim with paypal for refund as the dev is refusing to refund or communicate.
