[EX Q]: 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!
[EX A]: negative

[EX Q]: Keep your money! I bought this so I could check my husbands BP. I took it out of the package, set it up, and took his BP. The sphygmomanometer broke in the first use. I didn’t even get to finish taking his BP. It felt really cheap too. I also didn’t like that I couldn’t hook the sphygmomanometer to the cuff. It is part of the pump.
[EX A]: negative

[EX Q]: I'm very happy with this product. It's survived the entire summer season and still works like a champ. Varied spray nozzle pattern makes it easy to direct exactly where water is going. Timer is simple to use and effective. I would definitely buy again.
[EX A]:
positive
