Example Input: Looks good, easy, easy to assemble. Instructions and parts w/ Hex wrench included were shockingly easy to use and assemble. Overall solid parts, arms a little flimsy. Quality overall is very good. Head rest may prove to short even when adjust to it's highest position for people with broad shoulders and 'normal' torso length. Arms not very sturdy, not adjustable (I missed this in the description--my issue). Overall, for the price, will work for the time-being. Comfortable enough, but not a top tier product--quality = pricing so I'm happy.
Example Output: 3

Example Input: This pan was not perfectly flat so it does not work on a smooth top ranges. It appears to be very well constructed and would be an excellent choice for a gas range, I'm sure, so I had to return it.
Example Output: 3

Example Input: Very comfortable. Wide headband. Wide range of adjustability. The only problem I had with them is my glasses are quite large and get stuck inside. I must take off both the goggles and my glasses and then pry my glasses out of the goggles. I have this issue with most of the goggles I have used so it's just something I have gotten used to. Fast delivery and well packaged. I will order again.
