I've been with Nitroflare for quite some time. It's fast, dependable and the value for your investment is terrific. Go Ahead! You won't be disappointed.
I've been using NitroFlare for around 2 years now, have extended with them too.
I find them excellent, very fast speeds, no downtime (in the 2 years i've been with them).
Definitely a safe option and the only host I would consider using now.
2 BIG thumbs up from me.
