I just started playing here so my experience is very short. I did eventually use all 4 deposit bonuses that were available and I have to say they are very nice!
I might be bit biased since I beated wager in two of them but this casino felt really good overall. Slots were running hot and didn't lag at all. My first cash out arrived within 24 hours but it was made on Sat/Sunday night. Second withdrawal arrived in one minute! (This was made monday)

I played on this site few times. Every game worked well and no lag so there was no issues there. Site felt modern and good to use.
I was very luck and happy playing few slots that had endless bonuses so didint feel like i was being scammed by rtp/casino . I had trouble withdrawing my wins cause of making minor mistake during max bet by rules but it was resolved by casino guru and i got all my deposits back eventually. (it was smaller amount than i had won, but still felt decent after i made minor mistake during my bet.) Now im waiting for withdrawal for free spins without deposit and eventually this will make great difference in my rating cause if im getting payed 100€ for no deposit free spins which i
accumulated without depositing anything i will be very happy.
My withdrawal was accepted for 100€ without deposit. :)

I have played on multiple casinos under the same management.
My experience with Librabet has been the worst from all of these.
Everything works as in site and games are multiple and are working properly and no issues there.
My only issue is that i was given email and SMS advertaising 100% bonus deposit and i also saw that bonus on my account as claimable but after i made deposit i was told it was denied under managements decision. After that i played with my raw deposit and managed to make withdrawal, but its been now over a week and i have contacted support multiple times and im being told that they try to move it faster but nothing happens. In terms it says within 3 days process withdrawal requests but it seems to be atleast 8-9 days.

Edit here: I waited for 9 days and i was told everything is ok but now my balance was returned to my account and told to try withdrawal again due to technical difficulties. I was paid on 9th day after the request
