Andrew and Gordon went above and beyond for my girl, Freya's, car seat harness. Freya has a unique body shape being very long with such a deep chest, and they made her a custom crash safe defender harness and a longer car seat tether. Freya comes to work with me everyday and spend over an hour and a half in the car with majority of that being highway driving. It gives me SUCH peace of mind knowing that she is secure and as safe as she can be, if an accident were to ever occur. We couldn't be happier!

Andrew and his team are always kind and helpful. They genuinely care about your dog’s safety. They sized my dog for a harness and when it wasn’t quite right, they had us come into the shop to have the harness custom tailored for our boy, at no charge! Can not recommend enough!

We recently purchased the Optimus Gear Crash Safe Defender harness kit for our 65lb Heinz 57 Porch dog :) The business owner was extremely responsive & helpful in selecting the appropriate item & size for our pet & our special request for a rush was met well in advance of the date requested with the harness arriving in record time! The harness is constructed of premium materials & is extremely well constructed. The harness & service exceeded our expectations! We would absolutely recommend this harness & business if you’re looking for a superior quality product & excellent customer experience 🦮💖

5+++ stars! I am so happy my friend lead me to this car safety system for my dog. I have tried many over the years and nothing compares to this product. My dog is super secure, she can’t accidentally disconnect herself. She’s secured at two points of contact, can sit and lay down. The harness goes on with ease and the hardware used is solid. I am very happy and the system has given me much peace of mind.

I liked the harness so much I also bought the car seat cover. I am very happy with the quality of the cover, it stays put, it was easy to get on and it compliments to car safety harness system very well.

The service is also EXCELLENT! Andrew went above and beyond for me & my baby floof. They clearly care about their product, their customers and the pets!

I recommend this car safety system to anyone who takes there dog in the car.

I feel safe with this dog seatbelt. All products are great quality. Fits really well on the dog. Service is 100%, able to teach me how to fit the harness and the car piece. I suggest this product and this team.

The OG Bench cover is nothing but the best. The quality and durability of the material is excellent. It was extremely easy to install. Our dog Arie hopped right onto it no problem. Now we don't have to worry about all the junk getting our seat, no punctures or any other worries. Double bonus as a protector for our girl's booster seat! The flaps make it easy to buckle. And when we want to remove it, it's so easy to undo. Thank you!!
