Harvia M Series Wood Stove Sauna Heater with Exterior Feed

The Harvia M Series Wood Stove Sauna Heater with Exterior Feed features a glass door that allows the glowing fire to create a cozy fireplace feel. This unique design allows for the stove to be heated from outside the sauna, creating a relaxing ambiance while your sauna heats up on the other side of the wall.

The Harvia M3 SL stove provides strong steam for small home saunas. Its stone compartment ensures efficient steam and a quick heat-up time. With adjustable legs, installation is made easier - the smoke outlet can be easily positioned at the proper height. An optional chimney-mounted water heater is available for the stove. The exterior of the stove is constructed with stainless steel.

The cutest softest, quack, quack
Color: PINK
My seven year-old full octane energy 12 pound dog is obsessed with ducks every toy that she’s ever gotten really attached to has been a duck and I bought the same exact up from a different store at least a dozen times because she was obsessed with it. But as soon as she would get the noisemaker out of it, it was time for anyone. But it was so cheaply made I decided to start getting her different ducks that were supposed to be harder to destroy, and we still have a graveyard of destroyed ducks. But this one she doesn’t wanna destroy it. It only has one little squeaker is what I call it so she doesn’t care to try to tear it open and take it out. The material is extremely lush and soft and it is incredibly adorable. I don’t really know what makes it an interactive toy though, but I recommend it.

Puppy destroyed in days

My 5 1/2 month old Maltese destroyed this toy in a few days so I would definitely say it is not chew resistance.

Low/mid-tier toy at a high price point
Color: YELLOW
I have two pitbulls and they LOVE their babies! Sadly, one of them likes to tear their babies apart when he gets anxious, so it was time to look for some new ones. They seem to favor any stuffed animal can be "nommed" on (suckled), so when I came across this duck rope toy, I thought I'd give it a try! The toy arrived quickly, did not have any visible defects, and looked exactly as it does in the listing photos. It has a body filled with stuffing, crinkly arms, and a rope neck. There is one squeaker in the main body section. The minute the dogs saw me unpack the duck, they were at my feet and staring at me like "hand over the baby, woman." So, I did..... And they hated it :( For some reason, my dogs have totally rejected this toy... All they do is sniff it? They typically LOVE rope toys or anything that is elongated and allows them to play tug-o-war. So, I am not sure what the deal is with this duck. *shrug* Currently, this stuffed duck rope toy is listed for $10.49 on sale, down from the regular price of $14.99. I consider this toy to be low end to mid tier at best. It's something you would expect to find at your local discount/dollar store. Based on the lower quality, I think the current price is higher than I would be willing to pay for this toy. While the toy is exactly as depicted in the listing photos, it is nothing special and definitely is NOT "indestructible."
