I just bought the A55 from TechCrazy, and I’m really impressed! The staff were incredibly helpful and guided me through all the features of the phone. The purchasing process was quick and easy, and I appreciate the great pricing as well. The A55 is performing excellently, and I’m thrilled with my purchase. I highly recommend TechCrazy for anyone looking for quality tech at an affordable price!
Another amazing experience with Tech Crazy. First the iPad and this time an iPhone and both dealings were fantastic with lightning quick delivery times. Goods were exactly as described. Customer for good here. Thanks again.
Highly rate TechCrazy Manukau. Their Customer service was spot on from the get go staff were very friendly and informative, quality products and great pricing. My partner and I would 100% recommend to our family&friends. And would definitely return to store for future needs 😊
We brought our son a chrome book on Thursday morning and It arrived the next day from Auckland to taranaki, we spent $270.00 on a lenovo chrome book and as far as we are concerned money well spent with fast and efficient service and delivery. Very happy customer.
I ordered the S23 Ultra from TechCrazy to send to my friend in Canada, and the experience was fantastic! They processed my order quickly and managed to ship it out within just one day. My friend received the phone in perfect condition and is thrilled with it. The efficiency and quality of service at TechCrazy are impressive. I highly recommend them for anyone looking for fast and reliable tech purchases!
Visited their new Papatoetoe store today, and I was very pleased with the service. They helped me decide on the best laptop for my needs and provided a great discount too. They have all the payment options available, which is helpful. They also seem to have the best value on the market for pre-owned Apple products in NZ. Highly recommend.
