I have been using their products for a while now and I must say I am quite impressed. The quality is great and the prices are reasonable. The only issue I have is with their website, which can be a bit slow at times. Other than that, I have no complaints. Their customer service is also quick to respond and resolve any issues. Overall, I would recommend Btv technologies gmbh for their reliable products and good customer service.
