Wireless Dual-Tech Detector is een binnendetector die menselijke bewegingen detecteert. Met behulp van passieve IR en microwaredetectietechnologieën detecteert het apparaat de beweging van personen en detecteert wanneer ze het detectiegebied zijn binnengekomen. Door deze technologieën worden valse detecties veroorzaakt door thermische interferentie ook sterk verminderd. Het apparaat is eenvoudig te installeren en te gebruiken en kan direct op de app worden geconfigureerd.

Speaker broken
This toy is advertised as having a squeaker, but the one we had was defective and did not make any noise. Our dog still throughly enjoyed ripping this little duck to shreds through. The material was thicker than I was expecting but still only took our dog about 5 mins to completely destroy it (Golden retriever). I understand that this toy is marketed as for small dogs so I get that, but took away three starts because our came with the broken squeaker and for $10, you can find a lot better toys at TJ Max. This item is not a good value for our experience.

Durable duck toy for man’s best friend
Although it was suggested that this toy would be best for small breeds, I found that it’s durable enough for my 80 pound Irish setter! It has literally become his best friend. He takes it everywhere he goes! There’s a small squeaky noise that comes from the neck area that he has to work to find. I’m sure he will eventually destroy this as he has with all his other toys, but it’s really holding up much better than anticipated.
It is well worth the $10 cost.

Really cute, well made dog toy. Was a huge hit with our pup
This toy was a big hit!
Pros
- love the heavy duty burlap-kinda fabric. Our new puppy has razor sharp teeth but this fabric is holding up really well.
- size is great for a variety of breeds
- shape is perfect for grabbing onto. Our puppy especially likes picking it up on the neck where the toy is more slender
- the extra little feet and wing flaps add some interest that have really kept her occupied
Cons
- the squeaker is in the neck where the fabric has embellishments and is a little thicker. It's a little hard to activate the squeaker but maybe the toy/stuffing needs to get broken in more and then it will be easier to squeeze that section
