Hello! I have been going to Product Investigation Lab since about 1976. I still go to this day. Every time I go the staff is smiling, they are happy and very attentive to you on your visits. A very good experience and such an easy way to make money for those in need.



I have been coming to studies at PII for close to 20 years. The staff is amazing; friendly, professional, knowledgeable. I can not think of a time when I had a bad experience with any of the studies. And the staff always makes sure to follow up to see that everything is going well. Here’s to many more years together!



Thank you for the opportunity to participate in studies at Product Investigations. I’ve been doing them for the past 2 years and been fortunate to make some extra money from this. A friend introduced me and received a referral bonus. Can’t say enough good things about my experience. I love the flexible hours and the staff is great! A warm and friendly atmosphere.



PII has been a great experience! I started to make a little extra cash being a stay at home mom. It’s not only an awesome side gig financially but the products actually work!! You get to try top of the line products for free and make money while doing it! Everyone here is so sweet and welcomes my daughter and I each visit with lots of smiles! I have actually seen results with the products I have used and I’m always looking to do a new study for them!
