Friend told me to try, I stayed

Tried Kardynal in the beta becaus a friend invited me. Ended up using the prepaid card mostly for my grocery runs at Tesco, and it worked fine. The assistant is handy when I dont feel like scrolling thru dozens of product pages. The free trial made it low risk, so I thought why not — and I’ve kept it since.

Surprised it worked this well

I tested Kardynal during the beta and honestly didn’t expect to keep using it afterwads. What surprised me most was the AI assistant — it actualy saved me time when I was looking for a new pair of headphones, pulling up reviews and prices side by side. The card itsself worked fine at Boots and M&S, no issues topping it up. Felt smooth overal.

Beta experience was solid

I was a beta tester and could see the product evolve week by week. At the beggining there were a few bugs with the app, but support replyed within a day and things got fixed quickly. The shopping assistent isn’t perfect but it gave me some solid sugestions (found a decent deal on trainers thru it). I like the idea behind it and its getting better.
