Last year i contacted them for suggesting a light for my first attempt at a planted Aquarium. I was suggested Neo Helios XP 900. Prudent choice for a beginner and it worked well. This year i wanted to upgrade and they suggested Enguia. Although there was no review available on YouTube or anywhere, because of my earlier experience with them, i bought it to combine with my existing Neo Helios. They provided me technical support too as this light is programmable. On the first instance itself, three of plant varieties are pearling which indicates it was a perfect advice from them. Awesome support and genuine advice.
