Q: Now we are living a bark free life! Within two days it had cut out 99% of non-essential barking! At last you can feel peace and quietness in our house! We love our beagles but they were driving us crazy! It really detects barking from far away, now we don't even hear our neighbor dogs. Great quality and cute btw...This has been a life saver! We are able to get proper sleep now!

Q: These tongs are amazing! They have a great feel to them and are extremely sturdy! The silicon tips are easy to clean and hold up to high heat with no melting whatsoever. These tongs have a nice weight to them so they are not going to bend when picking up heavier things, such as a heavy pieces of meat. I like that they close and open by pulling/pushing the tab on the end of them. These are well made sturdy tongs and I would recommend them to anyone who is looking for a nice sturdy well built set of tongs!
