Pleasurable to Use, But Watch Charges

It was enjoyable to take the test and see my results, but I didn’t realize a subscription was included — that part was disappointing.

Good Questions, Unclear Auto-Renewal

The cognitive challenges were fun, but the auto-renewal terms weren’t obvious. I ended up canceling after an unexpected charge.

Not Clear Enough on Fees

I thought this was a simple one-time IQ test, but later noticed recurring subscription charges on my card. The billing wasn’t clearly explained.

Entertaining Test, Billing Issues

The quiz itself was entertaining and challenging, but after a small initial fee I saw charges on my account I didn’t fully understand. Make sure you read the fine print!

`Fun Quiz, Confusing Sign-Up

I enjoyed the IQ questions and the score report, but the sign-up process was confusing and it wasn’t clear what charges I was agreeing to. Watch the payment terms carefully.

Great IQ Challenge, Poor Billing Experience

The test itself was enjoyable and insightful, but seeing unexpected recurring charges on my card made the overall experience negative.

Good Test, But Problematic Aftermath

The quiz is solid and makes you think, but the unclear billing left me disappointed. I didn’t feel the payment info was explained clearly enough.

Mixed Feelings About This Site

I had fun with the questions and liked seeing my score. But I later got charged a subscription I didn’t clearly authorize. Not worth the hassle for me.

Entertaining Quiz, Billing Was a Surprise

The cognitive challenges were fun and well done. But I was surprised by subscription charges I didn’t expect — definitely read the terms carefully.

Enjoyable Test, Billing Transparency Needed

The IQ test was fun and well-organized. But I didn’t realize there was a recurring billing element until I saw it on my bank statement. More transparency would help.
