    Useful an woderful item. I use it for my colored led with a cuople of 3.7 v. li ion batteries. Very good packaging with clear instructions in chinese an english languages. Maybe wires to use are very thin but it is ok! I'm very happy for this, small an cheap ctrl.

    So this item is great, does what's advertised, but I've ordered a few of them for different purposes and the most recent one seem to function differently than the original I ordered. Whenever load is always on (mode 6.), the figure-8 indicator light on the device shows the normal indication, eg. power coming from panel and battery light flashing to indicate charging, but after 6-10 seconds the indicator lights up the whole figure-8 dimly, and stays like this until I either unplug the panel or battery,

    Agile DIY solution / На все руки модуль.

    It wonderful tiny controller for low power DIY solutions. It well build, have variety of functions, easy to adjust, works variety of batteries (VRLA, NiMh, Li-ion, LiFePO) in different combinations. Basically you can build everything from automatic lights and signs to 18650 solar charger, for about 10$. Be aware that there is no step-up or down converter build, so voltage will not exceed battery one. Highly recommend. _=_ Классный модуль для консруирования не мощных

    This is my 3rd purchased. Working fine for 3 years. Very small and I'm using it with my 9v solar panel and 6v Lead Acid Battery. Highly recommend for low power solutions.

    The UK magazine Everyday Practical Electonics had a very positive review of this in their September 2017 issue. Looking forward to build a solar project with this.

    Very good product and it was small than I expected. But it has smart features and great value for the price.The delivery time was not very long.
