The Havahart 5277 Critter Ridder is a motion-activated animal repellent that can detect movement and body heat from up to 100 feet away. It sprays a five-second burst of water to scare off critters. You can adjust its sensitivity, so whether you're dealing with little guys like squirrels or bigger animals like deer, you can tweak it to fit your needs.

According to the manufacturer's product description, this device runs 24/7 and is eco-friendly, using just 2-3 cups of water each time it activates. Setting it up is pretty straightforward since it comes with a metal spike to anchor it into your garden or lawn. Our research shows it's effective against all sorts of animals like chipmunks, skunks, and deer.

While it generally scores well for effectiveness, some feedback points out that keeping the fittings secure is important to prevent leaks. Plus, frequent activation might wear out the batteries faster, so be ready with replacements. Another thing to watch out for is the plastic parts; they might not hold up well over time or in tough weather.

So, if you're looking for a humane and green way to keep pests out of your garden, the Havahart 5277 Critter Ridder could be a good fit. Just know that it’ll need a bit of maintenance and careful setup to work smoothly.

It's a handy option for managing wildlife without too much hassle.

The battery life of the Havahart 5277 Critter Ridder can vary quite a bit depending on how often it's activated and the sensitivity setting you're using. Generally, the batteries can last anywhere from 2 to 3 weeks with regular use, but if the device is triggering a lot, you might find yourself changing them every 10 days or so.

The device has different sensitivity settings, which let you customize how it responds to different types and sizes of animals. This customization is great for targeting specific critters, but keep in mind that higher sensitivity settings or frequent activations will drain the batteries faster. So, tweaking these settings according to the usual activity in your area can help make the batteries last longer.

As a heads-up, there have been some mentions of the device's build quality in our research. A few folks noted that parts can leak if they're not properly secured, which might also cause the batteries to drain quicker. Making sure everything is tightly in place can help prevent these issues.

Although battery life might be a consideration, keeping an eye on your settings and maintaining the device can really extend how long it operates without a hitch. If swapping out batteries sounds like a hassle, using high-quality or even rechargeable ones could be a good move.

The Havahart 5277 Critter Ridder seems to do a pretty good job at keeping deer and other animals out of gardens and lawns. It uses motion detection to spray water at critters, which is harmless but effectively startles them.

According to our research, the gadget has an infrared sensor that detects movement up to 100 feet away. When it spots something, it sends a quick blast of water, making it an eco-friendly way to protect your yard without causing any harm. Plus, it only uses 2-3 cups of water per spray, so water consumption isn't much of a worry.

Feedback from others suggests it's successful at keeping animals like deer at bay. People have had good results after setting it up, but there are a few things to watch out for. You might need to tweak the sensitivity settings because otherwise, it could go off in the wind or from other non-animal motions, wasting a bit of water.

There were also a few mentions about the construction quality. It's made from plastic and metal, which seems decent for regular use, but if you plan to keep it outside in rough weather, it might not hold up as well over time.

Overall, it sounds like the Havahart 5277 does really well in shooing away unwanted wildlife. Just keep in mind, you might need to experiment a bit to get it working just right for your garden or yard.
