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.

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.

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

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.

I thought I was paying a one-time fee for the test, but later I saw subscription charges. It spoiled the experience — worth the test, frustrating afterward.

The questions were engaging, and I liked trying the quiz. However, the follow-up charges were unclear and felt misleading when they appeared later.

I enjoyed testing my IQ score, but the terms about recurring fees weren’t obvious. Make sure you understand what you’re signing up for before entering payment details.

The test was a good mental challenge, but the pricing structure wasn’t clearly explained. I got billed more than I anticipated afterward, which was frustrating.

The quiz itself was interesting and made me think. But later, I noticed subscription charges on my card that I wasn’t fully expecting. Be careful with auto-billing.

The IQ test questions were decent, but later subscription charges hit my card and I had to dispute them with my bank.
