I am a member of the same panel, via an email directly from Hilton Honours about four months ago.
Can confirm not a scam, and will happily vouch for their program. In the interest of disclosure I received 500 HH points just for signing up. Have not received any spam which I've been able to attribute to them, and the only messages they send are invites for the surveys.
The surveys are quite reasonable, and nothing worse than you'd usually get. Mainly about business/travel stuff, but may stray into other areas such as grocery buying habits.
The return on investment for the time spent varies, most surveys I've seen average a return of 300-500 opinion points. In as little as four surveys you have enough to make a transfer to your desired program partner.
I've been averaging at least one survey invite a week, and even if I don't pass the screener I'm still credited with 25-50 Opinion points. The numbers add up, and for a little bit of work now and again it's quite reasonable to earn enough to end up with nice bonus in your program of choice each year.
The points transfer works much like any other partner program for point transfers. You are issued points in their currency (opinion points in their case), for which amounts of these can be traded for a reward.
Rates vary from partner to partner, here's the list of partners and conversion ratio which I've manually extracted from their website:
- Air France/Flying Blue, Continental, BMI, Delta, Germanwings and US Airways: 4 OP - 1 Mile/point ratio
- Emirates: 10:1
- Hilton: 2:1 down to 1.6:1 depending on transfer size
- Iberia: 40:1
- Priority Club: Starts at 3:1, goes down to 2.5:1 depending on transfer size
You need a minimum of 2k in opinion points to initiate a reward transfer regardless of carrier/program. Once you have accrued the amount you wish to transfer, you log into the website and follow the process through the redemption section.
Points would be credited to the destination account as soon as all the stuff happens in the respective backends.
