output: Yes

input with options: Title: "Odd Ball" Review: The ball I received was warped and looked as though the seams were stretched and would burst at any given moment. This is a major flaw. This ball should never have made it past inspection and into the box for sale. It does, however, weigh 4 lbs, so they got that right. Is this product review negative?
output: Yes

input with options: Title: A great everyday blender Review: I've had mine for two years now and absolutely love it. I primarily use it for my protein drinks in the morning, and it has traveled all over the U.S. and Canada with me. The only drawbacks in the beginning were that (1) as others have mentioned, it is large and took some getting used to compared to my old corded hand blender, and (2) the instructions on the side ('press button to attach/detach') are misleading; it is not necessary to press the button to connect the pieces, and the first one I had felt like the connections got stripped when I tried to do so. Fortunately, the retailer permitted an exchange for a replacement. To attach the segments, simply push them together and it will work fine. You do need to press the button to separate the segments, and it can be tricky to pop out the plug to recharge it without breaking a nail at first, but once you get the hang of it this is a wonderful appliance.
