[Q]: Chairs are decent, we bought 3 for our office back in August 2018. One of the wheels came apart on one of the chairs, I sent an email 6 days ago with an invoice for our purchase and a picture of the faulty wheel to their customer service to ask for a replacement part, even if I have to pay for it, and have yet to hear anything back. Maybe this poor review will get their attention?
[A]: TERRIBLE CUSTOMER SERVICE! BAD WHEEL AFTER 4 MONTHS! NOT REPLYING!

[Q]: What drew me to this alarm clock was the sleek, modern mirror design. When I got the clock, it was really disappointing. First off, the quality of the clock isn't really there. It's light-weight and the material feels rather cheap. The power cord easily disconnects from the clock with every small movement. Also the buttons on mine were misplaced. The "M" button was suppose to be where the "-" button is. I figured that out after struggling to set up the clock with the directions. The time display is pretty bright, even on the lowest setting so if you prefer sleeping with minimum amounts of light, I would not recommend this clock. The best thing about this clock is the large time display. It's easy to read from far distances. The alarm function wasn't bad, just your typical alarm beeping sound. The alarm worked fine. I really wanted to like this alarm clock, but ended up being really disappointed.
