Disclaimers
Using a clutch kit with an unsprung clutch disc on a stock or lightly modified power engine that is daily/street driven vehicle can break the rivets on the clutch disc hub. Unsprung clutch kits are not designed for daily/street use or any constant on/off engagement environment. This can be compared to running a marathon in sandals vs a proper running shoe.

Fun toy for fetch
Size: Medium, Number of Items: 1
Daisy loves this toy. I found it from her dog trainer, and it makes rewarding her with a quick tug of war and fetch really easy. Also it’s shockingly durable. It looks like foam, but she has not destroyed this one.

Definitely recommend, great product!
Color: Grey
Absolutely amazing and great quality. My two chihuahuas have been digging and ripping up potty pads since they were babies. They are now 1 year and 3 months old and still do that. I tried reusable potty pads for a while and washing them, but eventually the smell and amount of time wasn’t worth it anymore. And I was looking for something else. I found these and ordered 3 of these potty trays and they are incredible. They can’t chew the disposable potty pads and they do great with this. I highly recommend! It took about 3 days for them to adjust to the feeling of the material but now they are comfortable. I wipe the top daily and change the disposable potty pads. Then once a week I clean with vinegar and water and towels or just soap and I sometimes spray down with hose outside. It makes it much faster and easier. It still takes work to keep it clean but it’s much better than cleaning up ripped up potty pads every day. It’s a great value also for the price and definitely I can tell is going to last a long time. For reference my dogs are 10 pounds, they are overweight right now and loosing weight, but this completely holds them and is very sturdy, even when both are on it at the same time. They use as their main bathroom area as it is not safe for them to go outside alone because there are coyotes in the area. And when I’m at work they have access to a potty area all day. I definitely recommend for dogs this size and am so happy I found a product that works for my home. Also the grey color is great and matches well in my home.

Absolute LIFESAVER.
Color: Black
A must-buy for any puppy owner that uses potty pads. Our pup still hasn't had all of her parvo boosters and has had to stay inside at all times. She is usually very good about going on her potty pads, but has a terrible habit of grabbing the pad and flinging waste everywhere and tearing the pad itself apart. This potty pad holder is PERFECT. It is sturdy and the grated tray fits in neatly. The dog is unable to get to the puppy pad, no matter how hard she bites or paws at the sides. Believe me, I've seen her try. We bought other puppy pad holders that were cheaper, but she was able to rip the puppy pad out of them easily. It is also really easy to clean. The plastic can easily be washed with soap and water or sprayed and wiped with antibacterial spray. The potty pad itself usually soaks up all of the urine, so there is never any worry of overflow. The only critique I have is that the rectangular shape is somewhat a poor design, because most potty pads are square-shaped. This means that the owner has to fold a standard potty pad in order to fit the tray. But this is not a huge problem, as we're still very happy with the product. Overall, it's worth the money, because now I don't have to worry about cleaning a huge mess, disciplining my pup for the behavior, or any health scares from her eating plastic from the potty pads. We loved the first one so much, that we bought a second one.

Perfect for what we need!
Color: Black
Love this. We have to leave our puppy home alone while we are at work. She’s tiny so I know she can’t hold it in the entire time we’re gone and I knew she would tear up the puppy pads. I came across this and it has been a game changer. She goes right on and does her business. One negative is when she only puts her front paws on and pees while half on the floor but that’s a quirk of the dog. The main negative is that if she poops, it’s sometimes hard to get it up and it gets in the holes. Plus is it’s easy to take apart and hose off. Definitely recommend!
