Super Responsive Team!

I had a great experience working with Ellie on the Flashbay Team. She was super responsive and helped walk me through everything, even when we had to make some last-minute changes. They have quality products that I have seen so far and we plan to use them again in the future

Eric was a great customer service person

Eric was very helpful to me when I had questions about the speakers I wanted to order for my company. The speakers with our logo's and our name on the bluetooth setting were a big hit. I would highly recommend this company as I was so happy with the customer service I received.

Bar Mitzvah Favors

We worked with Melvin to order blue tooth speakers, personalized for our son's Bar Mitzvah - he helped guide us in the right direction with regard to the image and we are so happy with the end result! AND...when Melvin was out of the office one day, Max helped us in his absence! No one missed a beat! Thank you to Melvin, Max and Flashbay!

Rhys at Flashbay was very helpful

Rhys at Flashbay was very helpful with my order and answering all my questions as well as helping me make the best decision for what I needed. The speakers we ordered are great, and Rhys was kind enough to send me a working prototype before I ordered so I was able to check the sound level. I look forward to working with Rhys and Flashbay again.

Bluetooth Speakers

We ordered these speakers as conference raffle items. They arrived on time and ready to represent the brand well. The customer service was exceptional.
