The Shure SM81 is a high-quality, unidirectional condensermicrophone designed for studio recording, broadcasting, and soundreinforcement. Its wide frequency response, low noise characteristics, and lowRF susceptibility have made it a standard for applications involving acousticinstruments, especially guitar, piano, and cymbals. POWER REQUIREMENTS NOTE:This microphone requires phantom power and performs best with a 48 Vdc supply(IEC-61938). However, it will operate with slightly decreased headroom andsensitivity with supplies as low as 11 Vdc. Most modern mixers provide phantompower. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Built to withstand the rigors of regular stage and studio use, theShure SM81 unidirectional condenser microphone is a great choice for studiorecording, broadcasting, and sound reinforcement. Its wide frequency response,low noise characteristics, and low RF susceptibility make it a perfect matchfor applications involving acoustic instruments, especially guitar, piano, andcymbals. Ruggedly constructed, the SM81 operates on phantom power and performsover a wide range of temperatures and humidity conditions. It comes with aswivel adapter, attenuator-switch lock, foam windscreen, and case for carryingand storage. Key Features Frequency response.

My puppy’s favorite fetch toy!
Size: Small
Update Aug 27, 2024: After 10 months, these are still his favorite ball. He’s obsessed with fetching and plays with them all day. They do bounce really high. Unfortunately, the small size aren’t available for sale anywhere anymore. I tried the medium size, and he has a bit of trouble hanging on to them, but he manages. Weirdly, he prefers the orange one, but he also plays with the blue one. My 7 month old Shih Tzu puppy loves to fetch, and these are his new favorites. They’re small enough to fit in his mouth, and they are made of hard plastic, so he’s able to hold on to them. They have a lot of bounce, and this adds to the fun for him. I highly recommend them.

Genuinely bummed that these great balls can’t stand up against my Chloè.
Size: Medium
I love all the Chuckit brand of balls. I found that the Strabo and glow balls in the Chuckit line are the softest, and as such, don't last as long as the rest of Chuckit line of balls. Having said that, they do last longer than than every other brand I've tried (and I do believe I’ve tried every brand available on the market today.) The strato balls do bounce higher than any of the other balls in the Chuckit line. They really are a good value.

Great dog balls at a great price
Size: Medium
The balls are a favorite for my dog. I could have done without the hole through the middle because I don't do treats in balls anyway. My dog loves balls for their own merit. I needed replacement balls for my Nerf Dog Ball launcher. It seems the originals have disappeared from the market. I took a chance because the price is right and this Chuck-it ball works very well so we're liking this ball a lot. So far my Dachsund, who can destroy a tennis ball (the kind they are selling as Nerf Dog replacements) in 3 minutes has not done any damage to this one so that's a win. I recommend this as a much better ball than the fuzzy tennis balls. I like the colors too since many dog toys are green (which gets lost in the lawn, etc.) or red (even though dogs have red/green color blindness. Blue and orange are good and pretty easy to find. I liked these well enough that this set was my second purchase so I will have spares in case the others are lost.

My Baby loves his new baby!
Size: Medium, Size: Medium
Finally! A ball my 107 lb. pitty/pointer mix can’t destroy. He has torn up every single “indestructible” toy in a day or so until now. He peels fabric and fur off non-rubber toys. He is a 4-legged shredder. I’ve added pictures of him for a size reference of my dog versus this product. I know I had wanted that when shopping for this item. This ball is now his beloved “baby.” He goes absolutely insane looking for it, chewing it, chasing it, and even sleeping with it. He won’t rest unless he knows exactly where it is. It is his only toy, and he is good with that. After getting this home, I tried giving him other choices, but he won’t touch them. I was worried that he would rip it apart by putting his teeth in the holes, but so far, not a scratch. It is soft enough to collapse just enough to keep it from cracking when his jaws crush it but not so soft that he can rip it to sheds. The holes are large enough to prevent a suction or vacuum effect on his tongue or mouth. For his size jaws, it is a perfect fit. Other dogs might have problems with suction or be able to get their teeth in those holes and rip it apart. Who knows? The older version of the Chuckit squeaky ball was his favorite for the year and a half he had it, but the way they make them now, he peels off the orange triangle in hours flat, the squeaker falls out (choking hazard), and then he rips it apart. I’m going to stock up on these. I can’t imagine how crazy he will be if they ever stop production or change the materials.

Perfect for my dog
Color: Blue Puppy, Size: Medium Size 2
My dog (16 lb) LOVES to whip her toys around and throw them in the air to chase after them. This is the perfect toy for her to play outside by herself. I would repurchase for her over and over again if needed!
