Example Input: So during 2nd Rifle season, up in the Colorado mountains, on Day 6 of the hunt.. mother nature decided to gift us with ~8 inches of snow. Finally, I had the opportunity to try out my Frogg Togg's and pull them out of my ruck. For the first couple hours, standing up right and walking through the snow looking for elk tracks, they worked great. They kept my legs dry and provided an extra layer of insulation. Despite it being around 13 degrees, my legs and torso were fine and I actually overhearing if anything after about an hour of walking in the snow. Then, we get back to the camp site.... We decided to throw on the snow chains to the truck in case we got can animal and needed mobility to move it. I took my first knee in my brand new, first time ever worn Frogg Togg bottoms... and the crotch blew out. Talk about disappointment. Maybe I received a defective product? Manufacturer/Amazon seller, please let me know if this is true. Or, is taking a knee while wearing these just out if the question? I was wearing 1 layer of thin poly pro's, one pair of super thin athletic pants (ADIDAS), a pair of Carhart hunting pants bottoms, and then XXL Frogg Togg bottoms when this happened. I felt like I was swimming in my clothing and was not expecting the crotch to pop. I mean, I could understand if I was wearing a Large, maybe even a XL, but come on..it was a 2XL. Am I supposed to be rocking 3 or 4X in order to be able to perform a simple function such as taking a knee? In closing.. thankfully the top I have is in good shape and no issues so far. Buyers beware. At least for the pants... which is what you need most! if I wanted to only protect my top, I would have went with my poncho.
Example Output: negative

Example Input: I bought this for my daughter and we were so excited about it. It worked for maybe 20 minutes tops... I thought that maybe my batteries were bad.. nope. We tried several different batteries and it still doesn’t work. It’s a cute puzzle, I just wish it still sang the song!
Example Output: negative

Example Input: As for delivery- it was great. Fast and came before my granddaughter arrived. I helped her put it on and the zipper would only go so far down. Then took it off and unzipped it but with difficulty. Put it on her and the zipper popped. My granddaughter is petite and the size is good except for that . She was so sad that she didn’t get to wear it. Very poor zipper. Was not happy that my granddaughter didn’t get to wear and enjoyed it.
Example Output:
negative
