Whether you’re a seasoned professional or a dedicated hobbyist, the GRR-RIPPER MAX offers features that elevate your craft to new heights, ensuring every cut is safe, accurate, and effortless.
At the core of the GRR-RIPPER MAX is its revolutionary Triple-Directional Force system, which delivers stability from every angle. This ensures that your workpiece stays secure and aligned throughout the cut. The downward pressure stabilizes your material, while inward pressure keeps it tight against the fence, virtually eliminating the risk of dangerous kickback. Forward pressure feeds your stock consistently through the blade, preventing burning and ensuring a clean, smooth finish every time.
- The GRR-RIPPER MAX is equipped with specialized 1/8″ and 1/4″ Legs, making it the perfect tool for handling small parts and performing intricate cuts on the table saw. Whether you’re crafting edge banding, models, or decorative inlays, these legs allow you to rip thin strips with absolute precision, safety, and repeatability. This capability makes the GRR-RIPPER MAX indispensable for projects requiring detailed work.
- The GRR-RIPPER MAX offers more than basic functionality. It’s a complete system. Inside the box, you’ll find the GRR-RIPPER PRO alongside every accessory Microjig produces. From the Stabilizing Plate, which offers 250% more stabilizing surface, to the Gravity Heel Kit with dynamic sacrificial heels that prevent tearout, every component is engineered to maximize your safety and efficiency.
- One of the standout features of the GRR-RIPPER MAX is the SafeRip Kit, designed to prevent blade contact with the pushblock’s Center Leg during rip cuts. This kit guides the Center Leg setting, ensuring it’s always in the correct position, reducing the risk of accidental cuts. The SafeRip Kit provides an additional layer of safety and makes your setups quicker and more precise.
- The GRR-RIPPER MAX isn’t confined to just one tool in your shop. It’s designed to work seamlessly across a variety of woodworking machines. On the table saw, it acts as a moving blade guard, offering unparalleled protection while allowing you to rip thin strips down to with complete control. On the router table, its powerful grip ensures command over your stock, whether you’re using the fence or freehand routing. When used on the jointer, the GRR-RIPPER’s Green GRR-RIP, material provides the traction you need for safe and effective face-jointing. Its ability to maintain a constant 90-degree angle on the band saw reduces blade drift, resulting in smoother, more accurate resawing.
- Fully Adjustable for Any Task. Every aspect of the GRR-RIPPER MAX is designed with adaptability in mind. The Center Leg adjusts to accommodate varying material widths, allowing you to maintain control over both the keeper and off-cut sides of your workpiece. The Balance Support adjusts to match material thickness, keeping the GRR-RIPPER upright and square, while the Adjustable Spacer increases the gripping surface by 54%, giving you greater control over larger workpieces.

Great entertainment, charges quickly!
Color: Orange
Super fun entertainment for dog! Toy ball charges quickly and the charge lasts for at least an hour of playtime for the dog. There are 2 modes. one mode Just lights up, which makes it easy for pet to chase it. The second mode not only lights up, but it also wiggles on the ground Randomly and speeds off in a direction on its own, which really makes it interesting for your dog or cat to follow! Once the ball is not touched for about thirty seconds, it goes dormant and it will stay like that As long as it's charged until somebody touches it, and then it starts up randomly lighting up and moving around the floor on its own And making a vibration noise. It's a lot of fun to watch the dog chase and play with, and it certainly keeps them entertained for a while! The laughs and fun entertainment are definitely worth it. The only downside is that my dog chewed off the soft fabric covering in about twenty minutes.And she's not a real big chewer. It looks better with the covering on it, but even without it, the ball works fine and she plays with it every day.So that is not a showstopper. But good to supervise your dog for safety.In case they are a chewer, and they decide to destroy the cover. But the ball works fine without the cover too!

Looooves her crazy new ball
Color: Orange, Color: Orange
Our 90lb mastiff/boxer mix Indie is very playful, curious and energetic. She needs toys that engage her and keep her busy. This ball does the job!
We’ve had it for less than a week. Here’s what I love and what could be better:
PROS:
• She dog loves it. She whines for it. She gets absurdly excited when I get it out. She’s a bit of an anxious dog, but had zero problems with it inexplicably coming to life.
• It lasts a while on a single charge, so it keeps her busy for a good long time. The longest we’ve used it at a stretch is an hour.
• It’s pretty durable. She’s a super chewer (destroyed every “non-destructible” toy we’ve purchased for her), but the actual ball is hard plastic. She gnaws on it and it gets scratches, for sure. But she’s not going to chew it to pieces.
• On carpet, it’s reasonably quiet.
• It comes with a replaceable silicone button.
• It’s easy to charge…just pull off the silicone button and the charging port is inside.
• The silicone button is flush with the ball’s hard plastic surface, so there’s no way for her to pull the silicone button out and swallow it or get to the charging port.
CONS:
• Cover is worthless if your dog is a chewer. It goes on like an envelope with a Velcro closure. We took it off immediately.
• Without the cover, it’s very noisy on hardwood floors. To us, it’s worth it. (Though, I work from home, so I might feel differently after the holiday vacation.)
• She’s an XL dog, so she can fit the whole ball in her mouth easily and accidentally chomp down on the button and turn the ball off. Not a big deal, just something to know if you’ve got a Lab or larger dog.
• With extended playtime, the two halves can come unscrewed, especially with a large dog who uses their paws/jaws on it a lot. Thankfully, it makes a loud buzzing noise when this happens, so we know we need to take it from her and screw it back together. Is this a potential danger? With the rechargeable battery inside, I’d say yes. But we also don’t let her play with this toy without supervision. So keep that in mind.
Bottom line:
It has its drawbacks, but it keeps her entertained and seems like it should last her at least 6 months with supervised play. Which is honestly REALLY good when we’re talking about Indie, Destroyer of Toys. I’d buy it again.

Difficult/impossible to unscrew plastic cups (in order to recharge the vibrating/blinking device)
Color: Orange
Generally, I don't leave feedback on items purchased. However, in this case, I feel compelled to do so in hopes the mechanical engineers (of this product) will take my input to heart and ultimately modify it.
First the pros...
- I have 2 high-energy dogs (Jack Russell Terriers) who love their toys (e.g., chewing bones, tug-of-war, etc.) but usually get bored with them rather quickly.
- This interactive PetDroid ball, however, keeps them busy for a long time.
- In fact, my smaller dog (Max) knows its storage location and sits (as early as 6 AM) in front of the cabinet so that I give him "his ball". It keeps him busy for up to 1-2 hours at a time.
- Max is literally addicted to the PetDroid ball... his determinant play with it makes me laugh all the time.
Now, the cons...
- After several days of play, the exterior looks chewed up quite a bit. That's no problem though.
- Unfortunately, the interior "threads/grooves" of the two plastic cups (for closing/fasting) are very tiny.
- Thus, after an hour-long hard play, it is almost impossible to unscrew the 2 plastic cups in order to recharge the interior device.
- It appears the 2 cups somehow come off track and get realigned from the inside.
- At that point, I cannot unscrew the PetDroid ball in order to recharge the device.... and without the blinking/vibration, this toy is no longer fun for play.
- Ultimately, I had to place the bottom half of the ball into a vise and then use a plumbing wrench to untwist it.
Proposed Solution:
- Increase the size of the plastic cups' interior threads/grooves so that they won't get realigned/come off track.
- This would mitigate the current dilemma of NOT being able to unscrew the ball in order to recharge it.
In my view, this should be a relatively simple fix and significantly improve the durability of this product.
Thank you for your time.

Good fun and entertaining!
Color: Orange
A really fun interactive toy for your dog! It's pretty erratic and really gets him chasing it. The included soft cover was kinda hard to install and then it's hard to turn it off and on with the cover on, I feel like the cover didn't really improve it at all, sure it's louder without the cover but I feel like dog also likes it that way, he likes loud squeaky toys and this thing making a bunch of noise is appealing to him. We have mostly hardwood floors so it really gets moving, I'm sure on carpet it would be a bit quieter and maybe even a bit slower to move around but on hard smooth surfaces this things can really get zipping around abd get some speed to make him chase it. Overall a fun and entertaining toy.
