I actually like videoslots, they have a great selection of games and their customer support is one of the best I have encountered for speed.
However they do have lower RTP on play n go games so you need to be mindful of this if playing there.
Never had any problems with them and the freeroll’s they offer are a nice feature that I have not seen offered by any other websites.
As many have said before once you have deposited just assume the money is lost as most of the time it will be regardless of which casino you play at.
But in terms of trustworthiness I would rank videoslots near the top end.
