I use them for about 3 years all been 2-3 times a week. I owns four. I love this product, easy to use, four different beam apertures 7 °, 14 °, 21 ° + a frost. 2 wheel 7 different colors so a huge range of color by mixing them. I plan to buy four more. In Cygnus the price is relatively accessible for product quality, very robust. He is 8 pounds I think this little trick for AC but a lot is done with and the fan is quite noisy but the noise did not disturb during my prestas. I never had a problem with (even of Cygnus) not even a bulb Petee. If you have the budget (which is very reasonable) does not hesitate.
