“I ordered the Flowtime Biofeedback Headband from Ubuy. I reside in South Africa. I was very impressed with the ease of purchase, parcel tracking, and speed of service. My package arrived much earlier than anticipated. I am very impressed with the service and would highly recommend it. Hence the 5 stars.”

“I bought Huckberry Flint & Tinder blazer at Ubuy. My request for a return was rejected at first but later I received an apology message willing to resolve the matter without placing any burden on me. I really appreciate their resolution. The blazer was collected yesterday by DHL couriers on behalf of Ubuy. They can only do a refund and not offer a bigger size as i expected, but i am fine with that too. ”
