70lb dog loves this kind of ball!
This is my dog's favorite style of ball! I have purchased others before, first from a local farm supply store and then others from Amazon, and this ball is of comparable quality to the others! The multi-tag design is great for my dog who love to tug and also to throw toys for himself. It's still inflated for now, but I'm under no pretense that it will stay that way forever. Part of the enjoyment my dog gets from his toys is in their destruction, and while we haven't hit that phase yet I'm sure it will come. This ball is great for medium to large-ish dogs who enjoy a ball that is kicked, thrown, or tugged!

So much fun
My dog is obsessed with this. It comes deflated and you have to pump it but it only takes like 30 seconds to pump. And it comes with the pump which is so convenient! It's nice because you can leave it a tad deflated so your dog can grab onto the ball part if you want. My dog has bitten it a ton and it hasn't popped or deflated yet so it seems sturdy. I like that there are multiple handles because not only does it make it easy to play tug o war but also then you can have multiple dogs playing with it at once. Has held up good over the past week and a great source of entertainment! My dog is about the size of an aussie for reference and it is perfect size for him and small enough for him to carry.

Can’t Take These Off – Ultimate Cozy House Boots!
Size: 12-13, Color: Fleece Black
Okay, I’ll be real — these Men’s Warm Up House Boots have officially replaced my old slippers. They’re insanely comfortable, super warm, and honestly, just make cold mornings way better. The thick Sherpa fleece lining is next-level soft; it feels like walking on a plush blanket ( and that's next ). I’ve been wearing them around the house non-stop ( in fact I'm wearing them now while i'm writing this review ) , and they keep my feet toasty even with tile floors and drafty mornings (New Hampshire winters hit hard). The non-slip soles are great too — I can walk from the living room to the garage without worrying about slipping. They’re flexible like socks but have that extra grip like real slippers. I also appreciate that they’re lightweight and breathable — my feet never overheat like they do in some bulky slippers. The design looks nice too; simple and cozy without being flashy. For the price, these are such a solid find. They feel durable enough to last through multiple seasons. If you’re the kind of person who wants that perfect mix of warm, soft, and practical, these are it. These are great for travel or outdoor lounging. These are a win for winter comfort!

Awesome slippers
Size: 14-15, Color: Fleece Black
Very warm and comfy, I have sasquatch feet (14 wide) and the 14-15 size fit great with plenty of room. It's very hard to find slippers in my size and these are awesome, especially for the price! Definitely recommend these, I've been wearing them pretty much daily around the house during this especially cold northeast winter and they're holding up perfectly.

Warm feet and ankles > everything
Size: 10-11, Color: Red/Black Check
So, I know the foam is going to wear out quick on these, but they are so warm I dont even care. I will update when they start getting beat up. But so far these are great. The soles on these arent the best. Its coushioned now, but even so my foot hangs off it. BUT, it is thick material and its keeping my feet and more importantly my ankles warm. Thats why I bought these. These isnt much on the bottoms to keep you from slipping hut what they have seems to be alright for now on hardwood floors. They fit true to size and are nice and stretchy, just beware the sole is a bit slim. For example my pinky toe hangs off it on both sides almost fully. Still a 7/10 would recommend for lounging around the house.
