I used to stream videos with Vimeo (old plan) and Bunny (which is really good). And I have to admit that Gumlet video as a new player is already very close to Bunny. So, I will slowly moving all my videos to Gumlet.
I bought tier5 with unlimited bandwidth, I'm not afraid of the future with Gumlet, they have shown in the past with Gumlet image that they know what they are doing and have delivered a lot for last past few years.
