Whats your experience with sponsors free hosting?
 

Some sponsors will give you free hosting if you only use it to promote their sites.
Whats your opinion on this hosting? is it usually rock solid, or is it up and down?

In the past I always had bad experienced with free hosting, but this time its sponsor specific hosting and wanted to know if anyone here has a good experience with it

It's usually at the same place they host their own servers, in my experience. And yes its in their vested interest to make sure its up 24-7 & fast.

usually you can't even link to other sites or anything...

so far i never had problem cause Fetish Hits has free domain hosting.

Depends on the sponsor.
From my experience PimpRoll has the best freehosting service around. Personally i never noticed any downtimes for my galleries.
There are also a bunch of other programs that give you decent hosting. Downtimes happen, but very rarely. Nothing that can hurt your listings at TGPs or MGPs.

my experience with it is good, I currently have a server at realitycash and it's working nicely :)
