Liam MacK –
Had some bad luck with a holiday and there was a supply chain mess going on worldwide. So, instead of the promised 5-10 days, it took longer for my expensive order to arrive, which made me a bit anxious. However, it eventually arrived, and the customer support was really prompt in addressing my concerns about the delay. All good here. I’m absolutely amazed by this jammer
