It's useful, but annoying in that it keeps opening windows wanting money or reviews. I went through the process of making an account and this nonsense in the hopes that they stop.

Leads to 100% CPU usage when nothing is going on. Not sure what it keeps processing. Anyone can check with about:performance.

What the hell is that QR Code in the corner? Why shold I pay for this??

you have to pay, otherwise it adds nasty QR to video and is very slow

It started nice but now you have to pay so you don't get a watermark. What a nerve this creators have. Now they're popular, they sort of oblige you to pay instead donating.

Gut

Era ottimo, quasi geniale, ora distrugge il video con un codice a barre e servono 18 euro per toglierlo senza nemmeno poter usare PayPal, tra l'altro ora scarica file da 1 minuto in 5 minuti mentre era velocissimo in precedenza, presto si mangerà tutto il credito che si era guadagnato e fallirà grazie alla cattiva implementazione ed all'avidità degli sviluppatori.
It was great, almost genial, now it destroys the videos with a barcode and you need 25 dollars to remove it and they don't even allow PayPal, also now it downloads 1 minute video in 5 minute while was light-fast before, this add-on will soon eat all the credit it earned and fail miserably due to poor progreamming and greed, it was a fun ride, farewell.

9 out of 10 downloads don't finish. It doesn't pause. It just ends with 10% or 20% of the video downloaded. You have to try countless times.

used to be good but through efforts to thwart these extensions it's become rather messy and convoluted.
requires a 'companion app' installed catch certain videos, which takes hours to d/l and convert. you might as well just install AVC which catches more than this and is over 10x faster.

Requiring a second download, in order to function. If I recall, it used to be a stand-alone add-on. However, I'm receiving a message that I need to download some other application, in order for DLH to operate.

Здравствуйте, отключите пожалуйста сочетание клавиш ALD+[arrow down/up] - это очнь мешает жить!

Most recent version is coy about which versions require the paid software extension and which do not.

It used to be the best around. Nowadays it doesn't offer an option to never convert any downloaded video. It forcibly converts any video you download (except for Youtube) and adds a watermark to it if the converter isn't registered.

The download button is a mess. It never used to be great, but it was good.

Need donate for removing Watermarks.
