This survey site takes a while to accumulate enough points to redeem ($50 Paypal reward = 40000 points) most surveys are worth between 700 - 1500 points. The surveys are always interesting and don't take too long to complete. You can also get rewards to use at Amazon, iTunes, Wotif, Flight Centre. This site also gives you the ability to donate your points to save a number of square meters of rainforest.

This is a great survey site with interesting surveys. I have been with them for just over 18 months and have redeemed $150 into my Paypal account and am nearly ready to get another $75 transferred. Its one of the few sites that also award you with loyalty points which is a % of the points that you have earned that month.

They don't issue a lot of surveys, you have offers to complete for companies to contact you regarding changing services (Internet, loans etc) which you will get points for if you are contacted and change. There is a guessing game that can be played everyday.
I think to get the most out of this site you need to shop online through there reward partners. If you like online shopping then this site rewards you for doing so.
You can have your points transferred from their sister site My Opinions and cash them out which takes 4-8 weeks or they have the instant egift card, which is emailed to you to then be used in stores like Woolworths, jb Hifi, Myer, David jones.

Takes a lot of surveys to complete to be able to redeem for a decent reward (I chose a $50 Visa card) it took me just over a year. The surveys are interesting but I find that they don't send out enough. If you have a bit of spare time here and there to complete them, then it's not really a bother the time it takes to accumulate point to redeem.

I joined this survey site about 18 months ago and am quite happy with it, I have redeemed $200 in Coles vouchers and have another $150 worth in my account ready to redeem for Christmas.
The surveys are interesting, the rewards for time spent are most of the time fair, I have had a couple that I have spent a few minutes on only to be screened out without reward, which is a bit unfair.

Very friendly and helpful service from staff that know what they are talking about. The prices are cheaper than the major chain store pet supply stores. I purchase 20kg bags of premium food for my animals and I never have to lift a finger, it's carried to my car by them, you don't get that service much these days. If your local, give them a try, you will not be disappointed.

Took my daughter there who was having bad chest pains, they saw her immediately and did a thorough examination ruling out the heart but ordered an ECG to be safe. The doctor listened to our concerns and answered each of them. The reception and waiting room was very neat and tidy. It's opens early and closes later than most doctors practices which helps if you cannot get there between 9-5.
