I recently purchased both a Quest and a Neptune kayak from Cambridge Kayaks. Unfortunately, the Neptune arrived with some damage. However, after contacting Cambridge Kayaks, they immediately arranged for the damaged kayak to be collected and, as soon as it had been received back, they promptly sent out a replacement. Their customer service throughout was excellent—friendly, helpful and efficient.
I also purchased the Heavy Duty Double Freestanding 2-Tier Kayak Rack. The only reason I'm giving four rather than five stars is that it didn't include any assembly instructions. I'm hoping to find these online, and I'm confident that if I give Cambridge Kayaks a call, they'll happily send me a copy.
Overall, I'm very pleased with my purchases and, most importantly, with the way Cambridge Kayaks dealt with the issue. It's reassuring to know that if something does go wrong, they resolve it quickly and professionally. I wouldn't hesitate to recommend them and would happily buy from them again.
