Input: Consider Input: This item was much shorter than I expected it to be. I have an alaskan malamute and this did not do the trick in trying to help with his pulling. If you have a small dog, this will work for you.

Output: negative


Input: Consider Input: Great helmet! Nice fit and great adjustments to get right fit. It’s very comfortable on and doesn’t slide around. Has good amount of padding. Great buy for the price.

Output: positive


Input: Consider Input: I purchased in June and hired an HVAC professional to install. After several calls to Nest support, it was determined that we had a faulty plate so we attempted to install the 2nd and again after several calls and a couple of hours, determined that that one wouldn't hold its charge long enough to install. In both cases, the window to return them had lapsed so I am out of $400 plus and then had to buy a regular thermostat to boot! Lesson here, do not buy this product until you are ready to install it!


Output: negative
