Review on 🔊 Powerful and Versatile: Kleinn Air Horns HK2-1 Complete Dual Truck Air Horn Package in Sleek Black Finish by David Boone

So I gave this 3 stars simply because Kleinn's customer service was exceptional. But the product itself isn't great - I would give it 2 stars. I had it professionally installed. The supplied compressor broke after about 2 weeks and I only used it a couple of times. Klein sent me a new compressor. It lasted 3 weeks. Both just worked, not really pressurizing the tank and never shutting down. This time Klein sent me an upgraded compressor. That worked well; fills the tank faster and seems to be of better quality than the first 2 I got. BUT. After 5 weeks the pressure valve failed. Luckily I had an extra valve from the second set that Klein sent me. In general, I've had a siren for about 3 months, I've tried 3 compressors and a shut-off valve. The Kleinn people were responsive and a pleasure to deal with; apologize and help. But the product just wasn't of the same quality as their services.
