How InSync Works

InSync Promise

InSync’s results are so consistent and effective, we guarantee them. Give us three months to solve your traffic challenges, and if you are not satisfied, return your InSync hardware for a full refund.

Dear Traffic Professional,

You are interested in InSync because you believe it will make a positive difference for your agency, your motorists and your community as a whole. We view your choice of InSync as the beginning of a long-term partnership. That’s because our goals and your goals are the same: reduced travel times, reduced emissions, reduced fuel consumption, and, most importantly, improved safety.

We take this partnership and our commitment to positively affect your community very seriously. So much so that, if after three (3) months of adaptive operation, you do not feel our partnership has had a positive impact in terms of reduced travel times, emissions, fuel consumption and improved safety, we will issue you a full refund for all the money you paid for Rhythm Engineering proprietary equipment.

Here’s all we ask:

After the three month period, if you do not believe our partnership is having a positive impact on your community, simply obtain an RMA number and return the proprietary Rhythm Engineering hardware to us in working condition within thirty (30) days and we will issue to the public agency a refund for all the money paid for that equipment.

That’s our promise – it’s that simple. 

We thank you for the opportunity to earn your trust and to serve your agency, your motorists and your community.

“The overall quality of performance and level of satisfaction we have with Rhythm Engineering’s support and operations led us to make the decision to incorporate the Rhythm InSync equipment on every traffic signal within Columbia County.”
