Why buy this
Buy this when a fixed practice lock is no longer enough
Clear locks teach visibility, but a repinnable cutaway teaches progression. You can alter pinning, practise a known problem, and then make the same lock harder as your tension control improves.
Visible but serious
The cutaway window shows the mechanism while the solid body feels more like a real cylinder.
Change the lesson
Repinning lets you rebuild the lock around standard pins, security pins, or specific problem chambers.
Longer bench life
One configurable trainer can stay useful through many stages of practice.
Practice route
How to use a repinnable lock well
Start with fewer chambers and standard pins, then add pins back in as the open becomes repeatable. When you are ready, introduce security pins one at a time so you know exactly what each change feels like.
- Record each pinning setup before you change it.
- Add difficulty slowly so feedback stays readable.
- Use the cutaway view to diagnose, then cover it and repeat.

Questions
Quick answers
Why choose cutaway over clear acrylic?
Cutaway locks give visibility while feeling closer to a metal cylinder.
Is repinning difficult?
It takes care and organisation, but it is exactly what makes the lock a long-term trainer.
Can a beginner use it?
Yes. Start with an easy pinning setup and increase difficulty slowly.
What tools help?
A pinning tray, tweezers, and a clear note of your current pinning make practice cleaner.
Choose Infinitus for a practice lock that keeps changing
It is the training lock for buyers who want visibility, metal feedback, and a way to build harder lessons on the same cylinder.

Good interactive toy that keeps even my poodle mix busy
Color: Blue
We have a poodle mix that easily gets bored with most toys, including the other interactive bouncy balls. This toy seems to keep him busy though and so far he has not destroyed it or grown bored of it. The only problem we have is keeping it charged because he seems to wear it out but it is not a problem to recharge it with the USB cable that is included. It is a little tricky screwing the toy back together after charging the battery but I am getting the hang of it. Once it is set to one of the play modes the ropes on top (that you need to put on) will start spinning back and forth and the toy gyrates around seeming like it is alive to our dog. The loves playing with it in all of the modes but I think he likes that faster modes better. It comes with an extra rope which was good because our raptor dog already ripped the first one apart. The price on this toy is relatively low compared to tother toys to I highly recommend this for anyone that has a dog who is bored with the typical play toys.

Great Enrichment Toy for Treats or Kibble!
Color: red
I love this toy—and so do my dogs! It’s perfect for daily enrichment and works great as a kibble feeder too. It holds a generous amount (about 3 cups), rolls smoothly, and keeps my dogs mentally engaged while they work for their food.
One of my favorite features is the adjustable treat holes. You can easily change the difficulty level, which makes it suitable for dogs of all sizes and skill levels. Whether you have a beginner or a more experienced puzzle solver, this toy adapts perfectly.
It’s well-made, easy to clean, and durable enough for everyday use. This has been a great addition to our routine and helps slow down eating while keeping my dogs entertained and stimulated. Highly recommend for anyone looking to add more enrichment to their dog’s day!

Doesn't break easily
Color: yellow/orange
This toy works really good. I bought it from my daughter's dog when they bring her over but it ended up the cat. Loved it and knows how to play with it. Better than the dog did. LOL

My frenchie likes it.
Color: yellow/orange
Very useful for my dog. It made him eat slower because he tends to inhale his food. He got his playtime and was able to eat his kibble a little bit a time.
