I use 4 Spot 575 moving heads that mark for more than 14 months, and I am satisfied with TRS. They came to replace lyres Robe Spot 250 XT I possdais for over 5 years, but despite their reliability dernires lacked power collection outdoor. The choice of this brand t dictated by the quality of the product and of course the price attractive trs. Only 3500 and the pair flight case, my choice for a fast t occurs because the era for that price I had a Lyre Robe 575 XT. So this year, I increase my stock lyre 575 Spot Light Control 8 in number, so they will associate my scan Robe 575 XT 6. Good job visually you can see on my site: www.starsystemdiffusion.com.
