Before I buy I tried the free version of livewebinar and the the result is :

I stacked 6 codes !!

The only thing I can say is that it's an awesome deal !

Streaming and recording are really good (I didnt test it with 500 participants) and livewebinar have a LOT of functionalities.

Though, the tool need some improvement for the French translations but it does the work.

I dont plan to use it right now but I didn't want to miss it because :

1. I tried the free version and you have to too if you are not sure what to do about this deal.
2. It's a LIFETIME DEAL WEBINAR with 500 participants (last time it was Webinarninja in 2016 with only 100 participants).

An other good point is the support of Livewebinar, the people are friendly and they answer quickly !

Conclusion : Dont miss this deal !

NOTE :
I read ALL the comments before buying the tool and what I see is that a lot of people are a little "agressive" because the deal is "too expensive" and they want to have it all for 49$ because it's Appsumo Community.

For exemple, I saw comments where people said that because the price is too high Appsumo and Livewebinar are losing money because people dont buy...

Livewebinar will lose money if there prices are too low and people buy.

I know that business who are on Appsumo have feedback on what they can improve and that's a lot of value for them and that's one of the reason that we have such good deals.

We all want the better for the cheapest price but we are all in business so what will you answer to someone who always ask to work more for a lower price ?

I hope that you will run away...

So even if it's not a 49$ deal and even if we have to stack to have more functionalities we have to welcome that kind of deals and I hope to see more of it in Appsumo !

PS : I usually dont write review because I dont have a really good level in English so sorry for those who have bleeding eyes because of me ;)
