Seen the prototype at Iwarna. Should be one and only in Singapore. First look at the gyre, the product looks slim and neat, definitely ideal to replace for some bulky wave makers out there. However, was skeptical on its performance due to its outlook but the prototype proved me wrong. The performance was impressive. The coverage and power are good. Depends on your placement, one unit can cover 2 ft width tank with ease. Therefore one can place the device vertically or horizontally for different coverage. Warning is when first use the device, it stirred up the particles in the whole tank and took a while for them to settle down, hence those with fine sand bed, beware. For the power, the mid range model can cover 5/6 ft display tank at Iwarna. One small issue with the prototype is the magnet holding the device. It was rather weak and hope the actual product has stronger magnet which I suspect will. Since the product is touching the shore soon, those who pre ordered the product, do share with us your experience. Those still considering, can drop by Iwarna to see the prototype in action and aid your decision making. Happy reefing.
