Productbeschrijving
De Dahua ARM9A4-P-W2(868) draadloze multi-IO-zender verbindt bedrade detectoren en sirenes naadloos met moderne draadloze systemen. Met 16 alarmingangen, 4 uitgangen, PoE, netwerkconnectiviteit en batterijvoeding is hij ideaal voor de integratie van bestaande systemen.
De draadloze Multi IO-zender maakt naadloze connectiviteit met de alarmhub mogelijk via zowel draadloze radiofrequentie als een bekabeld netwerk. Hij fungeert als een brug en verbindt de alarmhub met de bestaande bedrade detector en sirene. Hierdoor kunnen geactiveerde alarmen van de bedrade detector naar de alarmhub worden verzonden, die vervolgens commando's naar de sirene stuurt. Dit maakt het eenvoudig om uw bestaande bedrade detectors en sirenes te integreren in het nieuwe draadloze alarmsysteem. Hij bespaart kosten en breidt uw beveiligingsoplossing draadloos uit.

A few usability issues
My dog is obsessed with playing fetch. It’s part of our daily routine.
Pros
- I like that this comes with two launchers so we can keep one at home and one in the car.
- Build feels solid
Cons
- The cup is slightly too small for regular sized tennis balls. I buy the large Costco box of Penn tennis balls every couple of years for my dog. If you fully seat the ball in the cup/launching end, it’s extremely difficult to throw and puts some strain on your wrist. — the workaround is to only partially insert the ball when picking it up.
- Like others have stated, the launcher does come unscrewed occasionally after a few throws. It’s kind of annoying so I’ll likely try some thread lock, but ideally that wouldn’t be necessary.

Fun!!!
I can’t say enough good things about this tennis ball launcher! Roxy absolutely loves it. Every time I pick it up, her tail goes crazy with excitement. It’s so easy on my arm, and I love that it gives her a great way to burn off energy. The launcher is sturdy, well-made, and works like a charm. If you have a high-energy pup like Roxy, this is a must-have!

Fun along with frustration….
The product is good. The only problem is that the dark blue handle screws onto the lighter blue stick, and every 5-10 throws it comes unscrewed, and you have to screw them back tight. Maybe if they put a little bump in the handle and an indent on the handle so they could click into place it would work fine.

Great Value Toy
Color: Crinkle Duck (Blue), Size: Large, Color: Crinkle Duck (Blue), Size: Large
This toy has been one of my dog’s absolute favorites. He gets excited every time he sees it and will carry it around the house, toss it in the air, and keep himself entertained for a long time. The shape and texture seem perfect for him, and it quickly became one of his go-to toys over everything else in his basket.
What I really like is that it holds up reasonably well for the price. It’s definitely not indestructible, and after a lot of play, it will sometimes start to rip—usually around the feet first since that’s where my dog tends to grab and chew the most. But honestly, considering how affordable it is, I don’t mind replacing it when needed. It’s inexpensive enough that rebuying feels worth it because he genuinely loves it that much.
I’d rather keep buying a toy he is obsessed with than spend more on something that just sits untouched. It’s fun, cute, and keeps him happy, which is what matters most. Overall, I’d definitely recommend it for dogs who love plush toys and playful chewing.

Best affordable squeaker toy
Color: Crinkle Chicken (Brown), Size: Large, Color: Crinkle Chicken (Brown), Size: Large
my dog is obsessed with this toy, this has became his new comfort toy and after having this for about four months the legs are falling off but it’s very durable. The squeaker also moved from the head of the chicken to the body of the chicken but that’s after it was played with every single day. I love that it has two squeakers and it’s the perfect toy for my dog.
