Yikes, the delivery was incredibly slow and poorly communicated. Tracking information was minimal and updates were sporadic, leaving me uncertain about the arrival date. When the chair finally arrived, the packaging was damaged in several corners, raising immediate concerns about the internal components. Upon inspection, the build quality feels subpar; the upholstery stitching is uneven in places, and some of the plastic panels have minor imperfections and a cheap feel. The LED sensor light, a key feature, flickers intermittently and does not always respond to hand movements as advertised. The memory positions function, but the mechanism is noisy and jerky rather than smooth. Customer service has been unresponsive to my initial inquiry regarding these issues, which is deeply disappointing for a professional clinic setting. Overall, the experience has been frustrating, from the logistical headaches to the questionable craftsmanship and lack of support. This does not inspire confidence for daily clinical use where reliability is paramount. I had higher expectations for a unit in this category.
