Product Information
Automatic ratchet block
Now you can enjoy the flexibility of setting up your ratchet blocks to suit yourself. Ronstan is the only company that offers a ratchet block with both auto and manual engagement modes*. In the auto mode of the ratchet mechanism engages when load is applied, but switches off when it's released. This lets the sheet run out smoothly and freely-great for rapid easing of the sheet and for gybing asymmetric spinnakers. In manual mode, the ratchet mechanism can be switched on or off as required. This is the preferred mainsheet set-up for may top sailors. Try the block in both modes and see which you prefer - you really can't go wrong.
Selected Series 55 models.
Awesome ratchet block holding power
Quite simply, Ronstan Ratchet Orbit Blocks™ have the highest holding power available. The sophisticated NC-machined sheave features Generation 2 of our patented sheave cross-hole geometry. Its holding power is up to 21:1, almost double that of our nearest competitior. The unique sheave design has 12 gripping faces which directly resist loaded line movement. Traditional designes have only 8 faces with an angled resistance to line movement. Our Generation 2 design has straight resistance faces which both distribute the load and minimise rope wear. These faces are offset from the radial line, to draw the rope down into the gripping area when under load.
Materials
Sheave: Hard anodized Aluminum
Ball Bearings: High compression strength carbon black Aceetal
Frame/Cheeks: Toughened, glass fibre reinforced Nylon
Rope Link: UV stabilised, multi-strand impregnated SK75 Dyneema®

Okay little puppy pee plate. But some diy may be required.
Color: Gray
This little pup pee station is pretty good. With a little caveat. There's some pros & cons.
Pros: The back splash wall is very helpful. Keeping pee from going off the plate. But only as long as the pup aims that way. Which is why the little upright tube thing is helpful. I suggest placing it in the middle as close to the back wall as possible. Which leads to another pro. The little stick thing. It's hollow. A trick to help encourage your pup to use this is to place something your pup has peed on inside of that hollow tube. Or, you can see a bit on some cotton swabs & put them in there. The scent encourages your pup to pee there.
Another pro is that a medium size pee pad will go over the edges of the plate. You can either fold the pad in, or leave it overhanging to catch stray shots.
Cons: It is a little small. So this will only work for the smallest of pups. Another huge con is the grate on top. It allows pee to go through to the pad. But, most pups will refuse to step on this thing. So you'll likely have to get some of that draining fake grass to place on top of it.
So, in the end, it's functional, but you'll likely have to do some diy to get it there.

Good quality and helpful even if your dog doesn’t use it yet
Color: Gray, Color: Gray
Still hoping my dog will decide to use this, but even if not, it’s serving a useful purpose. I keep pee pads down for accidents, and I started by placing this on top to encourage my dog to use it instead. Right now, I have it next to our end table to protect it, and it fits perfectly there. I may try putting a pad on top to help with the transition. The quality feels decent for the price—the plastic is thick enough, looks nice, and the top stays in place without being difficult to remove. It’s practical, easy to clean, and works well for what I needed.

The Best Interactive Dog Toy My Dogs Won’t Put Down!
Color: Blue
I have a Labrador and a Jack Russell and I bought this Qraxond interactive ball mainly for my Lab’s strong hunting instinct but I was absolutely blown away by how both dogs went crazy for it. This toy isn’t just fun it’s a total game changer for keeping pups entertained stimulated and out of trouble when I’m busy.
The ball arrived nicely packaged with clear easy to follow instructions. It comes with a USB C charging cable for the internal motor no wall adapter included but any standard USB plug works perfectly. The bright blue color is such a smart choice it stands out everywhere so I never lose it in the yard carpet or under furniture.
Operation is incredibly simple. The inner vibration module is held securely in the ball with heavy duty velcro. Inside a rubber core vibrates and makes the whole ball move and bounce unpredictably. There’s a protective plastic flap covering the charging port just press the button once for low mode again for high active mode and a third time to power off. Super intuitive for anyone to use.
The build quality is solid. While it’s not designed for aggressive chewers and the seller clearly states that which I really appreciate it holds up amazingly well for normal play. My dogs love shaking it tossing it and playing tug of war with me and each other and the toy hasn’t shown any signs of weakening. The reinforced fabric loops are stitched tightly and make it easy for dogs to grab shake and carry even my Lab has a blast tugging on it and the vibration keeps him distracted from pulling too hard.
The motion activated vibration works incredibly well. It’s highly sensitive so it activates as soon as your dog paws nudges or moves it then shuts off automatically when play stops to save battery. Both speed modes are a hit the low setting is gentle but engaging and the high setting gets them zooming around. The random movement triggers their natural prey drive so they can play independently for 10 to 20 minutes straight something my people focused standard poodle rarely does without human interaction. It’s fantastic mental stimulation that tires them out without me having to throw a ball a hundred times.
It’s truly versatile for all dog sizes and breeds you can’t get more different than a Labrador and a Jack Russell yet both adore it. I ended up buying a second one just to stop them from fighting over it! The soft padded outer cover is gentle on teeth and gums and since the instructions note to remove the inner core before cleaning the cover is clearly machine washable making cleanup a breeze.
Battery life is impressive it lasts through multiple play sessions before needing a charge and USB C charging is as convenient as charging a phone. At under $25 this toy offers incredible value way better than similar products I’ve tried that cost twice as much.
If you’re tired of boring toys that get ignored or need a way to keep your dog busy and mentally stimulated while you work or relax this Qraxond interactive ball is a must have. It’s durable fun easy to use and loved by every dog I’ve seen play with it. Highly highly recommend one of the best pet purchases I’ve ever made!

My dogs love this ball
Color: Blue
This interactive dog ball has been a huge hit with my doodles — Simba, Roxy, and Ozzy! The second I turn it on, they go crazy chasing it around the house. It keeps them entertained, active, and mentally stimulated, especially on rainy days when they can’t burn energy outside.
I love that it moves on its own and keeps them engaged without getting bored after 5 minutes like most toys. It’s durable enough for energetic dogs and rechargeable, which is a huge plus. Definitely worth it if you have playful pups that need extra stimulation and exercise!
