Overview
The #1 EFI conversion system just got better! Introducing Sniper 2 EFI - a self-tuning, easy-to-install, EFI conversion for common 4-barrel (4150 flange) style carburetors. We took everything that we learned from the original Sniper EFI system and added 14 new features that will make your EFI conversion more simple, reliable, and modern. Like all Sniper EFI systems, Sniper 2 is designed to work with the Sniper Ecosystem that includes Hyperspark ignition, complete fuel systems, multiple user interfaces/dash displays, and more. New for Sniper 2 is the optional Power Distribution Module (PDM). This cost-effective and optional accessory isolates the core of your EFI and ignition wiring into one, easy-to-use location. Simply slide the stripped wire ends under the positive lock connector and tighten down the set screw. Battery and a switched 12-volt source is all that's required from your vehicle to power the PDM and your Sniper EFI. Make your classic drive like a modern fuel-injected vehicle, including easy cold starts, smooth drivability, and improved fuel economy! Sniper 2 is designed to be installed at home in your garage with limited tools and the support of Holley's comprehensive installation manual and videos. The user-friendly setup wizard allows you to answer a few simple questions about your engine and the system will begin self-tuning with no laptop or tuning experience required. If you're looking for a high-performance fuel injection system that delivers power, efficiency, and ease of use, look no further than the Sniper 2 EFI.

Great for cats, get rid of lip lifter!
Color: Microbrush Kit
The best toothbrush for cats! It fits and is easy to maneuver, and because it’s small, my cat doesn’t mind the shape. The only thing is that the lip lifter hits teeth and gets caught in cheeks, so I sanded that off, which has made teeth brushing much easier.

Soft brush, good quality!
Color: Microbrush Kit
I like that the bristles on the brush are very soft and it's curved well for my kitty's mouth. The only thing that I don't care for is the handle is pretty long and doesn't need to be.

Best best pet toothbrush I have tried
Color: Microbrush Kit
This is by far the best toothbrush I have found for my cat. It was clearly designed by someone who deeply understands feline dental health. The way the bristles decrease toward the tip and the specialized part for lifting the corner of the mouth are incredibly thoughtful and effective features. While the bristles are soft, they are strong enough to provide the necessary pressure against the teeth. My cat has a relatively small head and mouth, yet she resisted this brush the least of all. I will not be going back to my previous toothbrushes. Very highly recommended!

Cat approves, easy to use, comfortable to grip, sturdy.
Color: Microbrush Kit, Color: Microbrush Kit
My cat seems to love it so that's a automatic win! I was a little unsure about using a long handled toothbrush, I thought it would be more difficult to use but turns out its actually easier than the little finger brushes. The heads on the toothbrushes can be swapped, making it so that you dont have to buy a whole new one. It's been a few months since I bought it and its holding up well, no major wear on it aside from some gnaw marks from my Chonk chewing on it. Fits nicely in my hand and the brush head isn't too big for my cats tiny faces & teeth. I'd recommend it so far and I'm going to keep on with this brush instead of trying a new product every time.

its packaged nice and it is a smaller product to fit in kitty mouths but still not great.
Color: Microbrush Kit
it's a nice product but still doesn't make my cats any easier to brush. Nor does it seem enjoyable. I enjoy brushing my teeth and I want them too also. I believe cats life would be so much longer if we brushed their teeth. Think about how early our ancestors died before proper dental care.
