After posting my initial review (see below), Critter Guard contacted me to offer an additional set of rollers and wheels to supplement the existing system. We decided to install three more rollers to the electric line, with an extra wheel on the roller from which the squirrel parkoured. We decided to add two rollers before the first wheel so that the squirrels would have to first get on an unstable surface before attempting to jump the first wheel.
So far, I've seen no squirrels attempt to get to the house via the electrical line, though the weather has not been conducive for squirrels wanting to get on the roof (either blazing hot or pouring rain). But I'm optimistic that this extended setup will help to deter the squirrels from getting to the roof from the electrical and FiOS lines.
The customer service from Critter Guard is impressive. Our first package didn't include the hot line clamps we'd ordered. I called Critter Guard, and they sent them next-day air so that our electrician could install them the following day. Getting an additional set of rollers and wheels to make the system more suitable for our acrobatic squirrels was a very generous and much appreciated gesture.
Our electricians had never installed something like this, but they found the system easy to install. The installation instructions are good, and the videos make them better. Both electricians asked us to share any videos in which we catch squirrels falling off the electrical line. I can't wait to capture such a video so I can share it far and wide!
Initial review:
I like the product. It was fairly easy to install, and it looks like it should have deterred squirrels.
The squirrels definitely hesitated for a bit. But then they leaped over the wheel, parkoured off the middle roller, and leaped over the final wheel to the open wire.
At least it slowed down the squirrel highway. Maybe more rollers would cause them to not be able to cross. Maybe a roller with a wheel in the middle, so that they need to get more air. Or maybe that would just train them to be more acrobatic than they already are.
