What our Valuable Customers Say about us.
Techcrazy Reviews
The service and respect shown to me by the person who took my call, prompted me to place the order as soon as I got the email with details on it. I was querering the freight to the South Island, and he did not make me feel stupid, rather explained it me. I really appreciated his honesty and interest in ensuring I had a good dealing with Tech Crazy. This was my first time buying from them and I will be checkingh their prices when ever I want more Tech gadgets.
Staff were polite and although it took a little while to get my product (which was my fault as I'd originally asked for it to be couriered and decided I couldn't last without a phone and picked it up) I got what I wanted and it was what I expected. Maybe they could be a little more outgoing but otherwise excellent service
I m thankful to TechCrazy store to meet. My kids needs specific laptops for school, and TechCrazy not only had the exact models we were looking for but also offered great deals and discounts. The staff were knowledgeable and helped us choose the perfect laptops.
