New hair supplier suggestions? Nano rings

Any recommendations for a good supplier who offers nanos?
My current one is pretty good quality but sends out wrong shades and doesn’t not have great customer service. Thanks!

Prestiege are really good, never had any issues with colour or quality. I have thier nano rings in my self.

I fitted prestige nanos about 2 months ago and the hair was lovely. Down side was they were natural ratio so a bit thinner.
I’ve been using prestige lately due to a supplier issue and so far so good x
