Description
NRF905SE Wireless Transceiver ModuleThe nRF905 is a radio transceiver IC similar to the well known nRF24L01, but operates at 433MHz instead of 2. 4GHz, has a much longer range and a few extra IO pins. However the nRF905 data rate is only 50Kbps compared to nRF24L01s 2Mbps. Features: The tri band transceiver, operating frequency of the international ISM band 433 868 915MHz GMSK modulation, anti interference ability, especially suitable for industrial control applications using the DSS

Dogs love the treats hidden within
Style: Chilly Penguin, Size: Small (Pack of 1)
The treat holding penguin is ideal for feeding treats, frozen and otherwise, to your loving pets. I have put yogurt, applesauce, mashed bananas, and other treats inside the penguin. The puppies love licking the yummy treats out of the penguin. It occupies them for quite a while. The only thing is that they are not very easy to clean. I use a small soft brush after soaking them in hot water.

wonderful - best dog toy on the market!!
Style: Chilly Penguin, Size: Small (Pack of 1), Style: Chilly Penguin, Size: Small (Pack of 1)
my 10.6 lb shih tzu mix loves these. yes, they are durable. this is the third dog on some of them. i fill with diluted baby food mixed with 3 drops honey, carrots in todays, or peanut butter and a tad of jelly mixed with water, or water with unsalted cooked veggies like broccoli or cauliflower stems and carrot bits, or baked and mixed with water sweet potato. she eats just anout any vegetable. the water is to reduce calories as i had to take 3 lbs off her when i got her. and yes, they stack nicely.
when i let her out of her crate, she looks and grabs it and puts it on the kitchen floor for a refill. her idea, not my training but i like it.
this is an addition to my previous review. as far as i'm concerned, this is the best toy on the market for very small dogs. my dog has been at target weight for 2 years now and i restrict her treat calories to a strict 21 kcals daily. she is also now a working dog. i have now done frozen greek yogurt with apples and blueberry baby food diluted, kibble mixed in water. wet dog food diluted with water etc. i leave her in her crate with one and two cameras on her, one two way audio and she has stopped all barking and dutifully brings the toy and actually deposits it in my hand when i let her out of the crate. every 2-3 days it's like a new toy flavor and no toys have and tooth marks or anything on them. they're used daily.
understand this lil 10.6 lb dog goes thru nylon power chews regularly so she's super capable of destroying toys but i think the little bit of food satisfies her with the penguin and 2 1/2 years in, she has no desire to destroy them. i now own 8 of these as 2 stay in her travel bag.
we would be heartbroken if the company quit making these penguins. fantastic product. the small would even have worked for my 5 lb papillons had they made them then.

Great durability and utility
Style: Chilly Penguin, Size: Medium/Large (Pack of 2)
I love the size of these and the sturdiness. I freeze bone broth and put it in the crate or give it to dogs when it gets warm out. To help them cool or help them with teething. They have decimated other holders of frozen liquid, but these have lasted well. They also do not get sharp edges when chewed on by English bulldogs.
