They are advertising the new Z Fold 8 ultra. We have the Z Fold 7, so we went there to check it out ans to buy a new mobile. I asked to see the phone because, in stores, they usually let you see and touch the phone before buying it. The guy replied in a really sarcastic way: βAs I am the professional here, I can confirm that it is a good phone.β I was like: βWhat?β Then I showed him that I already had a Z Fold 7 in my hands. He replied: βSo, you already know that it is a good phone.β Again, I was like: βWhat?β So I explained that I simply like to see and touch the phone before buying it. He just told me: βOK, go to a big store. We donβt have the phone here.β Wellβ¦ not recommended. Even though Iβm a big Samsung fan, I still want to check the phone for myself before buying it. Itβs up to me. Expertise on something? ChatGPT also has expertise and will probably tell me much more than a sales guy.

Zero stars if I could. I purchased a fitness tracker from this store that failed to perform its most basic advertised functions. It would not reliably track steps, sleep, or heart-rate data, and the battery life was nowhere near what was claimed. When I returned to the store for assistance, I was told the device had been checked and was supposedly working correctly. However, the problems continued exactly as before. Despite the tracker clearly not functioning as expected, the store refused to offer a replacement or further assistance and instead told me to deal directly with the manufacturer. This is extremely disappointing customer service. When a product sold by a retailer appears to be defective, customers reasonably expect the retailer to help resolve the issue rather than simply pass responsibility elsewhere. The most frustrating part was not the faulty device itself, but the complete lack of support once the sale had been made. Based on my experience, I would strongly recommend that others think carefully before purchasing electronics from this business, especially if after-sales support and customer service are important to them.

The staff were really helpful and they knew a lot about their products. 10/10 I'd definitely recommend this store. Also, it is the only place in St. Paul's Bay selling Kodak, Polaroid cameras and digital cameras.
