Ipsos Knowledge Panel?

Thurrafork

Hello folks

Recently got invited to join Ipsos Knowledge Panel.
I don't really know anything about survey organisations or how handy they can be, but if I can make a few extra quid here and there then I'm probably up for it.
But does anyone know anything about this one?
A google search led me to believe it is not dodgy in any way, but I did find a few negative comments about it here and there - but that was mainly a US site.

Is anyone here a member of Ipsos Knowledge Panel?
Is it worth accepting the invitation do you think?

Thanks

I've been using Ipsos surveys for a wee while.  Not great payouts for the effort.  Also let them collect data from my phone, but not seen what the rewards are like yet
