Be it in a case, on radiators or heat sinks – Features like the silence-optimized fan blades and the funnel shaped fan frame make Silent Wings 4 140mm PWM high-speed a fan that makes no compromises between very quiet operation and highest performance.

OPTIMIZED FOR HIGH-END PERFORMANCE
Minimum tolerances for maximum air pressure
Silent Wings 4 140mm PWM high-speed makes for extraordinary air pressure and, therefore, significant increases in the system’s performance. The decreased distance between the fan blades and the frame makes it possible. By that, the Silent Wings 4 140mm PWM high-speed allows the user to run even the most demanding applications.

DIFFERENT MOUNTING OPTIONS
For any purpose
Silent Wings 4 140mm PWM high-speed has 2 mounting options in the scope of delivery. The pre-installed anti-vibration mounting reduces noise-generating vibrations to a minimum. For radiators and heat sinks, the plastic mounting is the first choice. Both solutions have in common that they enable virtually inaudible operation at regular speed.

6-POLE FAN MOTOR
The key for virtually inaudible operation when needed
6-pole fan motor with 3 phases for very low power consumption, less vibration and therefore quiet max. operation of 29.3dB(A). Equipped with this state-of-the-art technology the fan is virtually inaudible when operated in mid-speed.

FLUID-DYNAMIC BEARING
The advanced fluid-dynamic bearing (FDB) enables a super long fan life of up to 300,000 hours. In addition, it reduces the vibrations significantly and supports the virtually inaudible operation of Silent Wings 4 140mm PWM high-speed.

ELEGANT LOOK
Magnificent appearance from all angles

So far this is the perfect alternative to other wobble toy feeders. Please make a bigger size!
Size: 1 Pack, Style: Pawbler
Why did you pick this product vs others?: I bought the Pawbler because the two most popular wobble treat feeders on the market are plastic, and one of my dogs just absolutely destroys those in no time because he bites them and throws them rather then nudging them and then he has plastic cutting him so I am forced to throw away a costly treat toy/dispenser. I thought maybe a rubber one would work out better. So far my dogs love it, it works well spitting out their kibble, seems to be holding up and is easy to clean and feels like a good weight, not a super flimsy toy. I would love to see it made in a slightly larger size, I think this current size is good for medium dogs. It holds just under a cup of small round kibble but I would like to see one that can hold more and is slightly larger in size. I have 4 german shorthaired pointers, my test subject for this toy is mostly my 70 pounder who bites the toys instead of nudging them and throws them across the room, so it is taking a beating. I think for him a larger size would be helpful in deterring that behavior but I also think this may be too small for larger breeds. Durability: So far this toy looks just like when I bought it. It has no punctures or scratches and unscrews without problem. We have only had it a week or so but we use puzzle/toy feeders to feed our dogs lunch every day so it is pretty easy to tell which toys won't last long. Obviously, I can't speak to long-term durability at the moment, but I can say that most toys similar to this end up already scratched or punctured in a few days, so this is already sturdier when compared to what I have tried before.

Well made and durable, not a toy the pups seek out
Size: 1 Pack, Style: Tug
Well made. Thought our staffies would love since they live tugging with each other. Sadly not something they seek out. We love ALL the benebone chews though!

Durable fun enrichment toy
Size: 1 Pack, Style: Pawbler
I had been wanting to buy one of these kinds of toys for some time but thought that the other brands I had seen were too pricey so this was a great compromise for the price. My 5 yr old Portuguese water dog loves it. He spent 25 min playing with it the first day. The trick is to find a treat that is just big enough where it doesn’t fall out right away so it makes it challenging and fun for them. He has been chewing on it a lot for a week and it has not broken or shown signs of damage. One thing to note is that there is a small hole on the bottom of the toy so you cannot freeze liquids in it without covering the hole in some way so that would be my only complaint. Besides that it’s a great toy that keeps him busy and happy.

Dog doesn’t care for it
Size: 1 Pack, Style: Bone
Hard to review product for its durability because my dog has never chewed it once. Doesn’t care about it at all. The bone feels rugged but smells like playdoh. It’s sat on the floor for over a month untouched.

Pawbler FAIL: First time our dog bit the ball, it popped open and dumped all the kibble.
Size: 1 Pack, Style: Pawbler
I would not recommend! We have a 48# dog and within minutes of giving it to him, the Pawbler was open and all of the kibble was in a pile on the ground. I had washed and dried the Pawbler, added kibble, and tightened the lid as tight as possible. Imagine my surprise when, within minutes of giving it to him, the lid was off and all the kibble was on the ground. I thought it was a fluke so then I made an extra effort to make sure the lid was super tight...and the same thing happened. This time there was no food inside so he started chewing on the two parts. Within minutes of that, he'd chewed/damaged the rubber on both the body and the lid. I took it away as I didn't want him to destroy/eat any of the rubber bits. I was surprised he could even get the Pawbler in his mouth. It's heavy and he is a medium sized dog. He has the Benebone Bone, the WestPaw bone, the WestPaw ring that he chews on all of the time and none of those are showing any type of wear so to see this opened/chewed within 15 minutes makes me think this was defective. I am returning and hoping for a refund. DO NOT BUY! Poor value for the money. Not durable. Not chew resistant.
