This thing is amazing and is changing the way I work. I’ve been sitting behind a desk for the past 9 years and the last 5 days, I was able to stand and work for big part of the day. The shipment came quick and I give it 5 stars for value. If you didn’t know, It comes in a very small box which kinda freaked me out at first. Don’t let that scare you. It’s very easy to put together, although when you first open it and look at all the pieces, you may think it would be hard. It took me about 1 hour to put it together by myself. The directions were some of the better ones I’ve had in the past 5 years. All in all I, love it and would buy it again in a second if I needed to.
