Delivery and packaging very fast, safe and stable. DIY assembly child's play and super bright. The construction is well thought-through and very precisely tailored. By far the best DIY kit on the market, a clear recommendation!
    I just had the pleasure to be advised by phone. I've NEVER received such good advice (no matter what it was). Here people are convinced of their products. Professionally incredibly savvy and interested. Actually had only a few questions, it has become a consistently friendly and profound advice that leaves nothing to be desired. I have now decided on two 300 watt DIY kits as well as two Far Reds and can hardly wait for the delivery. Actually, the advice was already worth the money. If the articles are only half as good as the service, the purchase will not regret a second. Absolute top service. 12 points goes to PRO-EMIT
  • I have been using the 300 watt DIY M-KIT for two weeks and am very satisfied. Dimmed at 50%, the temperature is 23 degrees. I have further expanded the set according to my requirements and it is growing and growing. Perfect. Thank you especially for your TOP service. Quick and personal answers from people who have a clue. No cheap China reseller. Keep it up!
