So far I haven't used the product, but it will be going in my grow set up next run, I have started my journey on replacing all my ac infinity equipment and hope to have all my equipment switched to Mars Hydro very soon. The service has been amazing and they have answered my every question and have went above and beyond, delivery was spot on no problems and no delays at all, and as for Quality if you have ever used any Mars Hydro products you know it's all good.
