Way better than the M size for us
Like most people that have dogs I first went with the M size or Tennis ball size (about 2.5") chuckit for my 65-70 lbs Lab. After having that for a while and my dogs' evolution from liking to chase the ball to wanting to catch it, I started seeing how the M size could cause some life threating problems for my pup. I was on the fence for several weeks when I came across this option that included a 3" ultra ball as well as a 3" fuzzy tennis ball like ball. These balls can fly so much farther with less effort and my furry friend seeming to like them more than the 2.5 inch. It also seems to fit their mouth better allowing them to enjoy 'the game' (you lost by the way) much more. If you have a larger dog or your dog has a big mouth, please trust me when I say skip the 2.5" M size balls. You and your dog will haves much more fun with this 3" size

Chuck it ball launcher
This is great! I have a blue healer that loves it. She will play fetch with the ball all day long. The launcher is easier on my shoulder. I can throw the ball twice as far and when she brings the ball back I can grab it with the launcher without touching a spit covered ball. Awesome buy!

My favorite pimple patches
Model: Hydrocolloid, Size: 102 Count (Pack of 2)
I love these pimple patches!! They are so invisible on my face and perform decent under makeup, they're super thin so you don't see the bulky outline of the patch, and they are so durable! I don't have any lifting on the edges of the patch throughout the whole day. SOOO easy to use with the way you can peel half of it at a time, so you don't have to worry as much about getting it stuck on your fingers before putting it on your face. This two pack lasts forever too!! Definitely getting your money's worth.

Invisible, Reliable, and Weirdly Satisfying
Model: Hydrocolloid, Size: 102 Count (Pack of 3)
I’ve tried a ton of different pimple patches and some fall off in the middle of the night, some look like you’ve taped a sticker to your face, and some just straight-up don’t work. These? These are my go-to. I wear them day and night, and I’ve literally forgotten I have one on because they’re that invisible. Even under makeup or in bright lighting, it’s hard to tell it’s there unless you’re seriously up close. They adhere well with no random peeling or slipping off and they stay put even through sleep or light face washing. That alone makes them worth it. But beyond just staying on, they do the job. After a few hours (or overnight), you can actually see the patch pulling oil and gunk out of the spot. It’s gross in the best way. I’ve had whiteheads flatten out and redness reduce without me ever touching the pimple. No popping, no scarring. If you’re the type who picks at your face out of habit that this helps break that cycle. Just slap one on and forget it. I’ve genuinely missed them before because they blend into my skin so well, even in the mirror.
