Jebao Programmable Auto Dosing Pump DP-4, Black

This Doser is super awesome and for the price you cannot beat it. Do not expect anything fancy, it works, and it is accurate. It is just a couple of boards with a shell connected to dosing heads. No fancy apps or remotes you just set it and forget it. One thing to keep in mind is that if you have issues with it not keeping the schedule and time you set that you may have to replace the internal memory battery or make sure the contacts on the battery are not bent out of shape. In my experience, I set it and when I unplugged it would reset the time and schedule. I then opened it to check to see if it had a battery and it did. I checked the battery, and it was reading the proper voltage. I noticed that the contacts were barely touching, so I bent them slightly and it worked as advertised.

Très bon rapport qualité prix

Zaskakująco skuteczne i łatwe do ustawienia. Polecam ;]Ciągnie płyn z minerałami 2 metry w górę i nawet dobrze dawkuje do akwarium!

Excelente inversión para acuarios plantados, no vuelves a dosificar manualmente. Es precisa, muy buena calidad y mantiene la programación si se va la luz. Dosifica por mililitros, defines cada cuántos días se ejecutará. No permite programar de acuerdo a los días de la semana, tienes que adaptarte.Meses utilizándola y las plantas como nunca antes. Fácilmente puedes cambiar un valor y esperar para ver resultados con precisión.

I purchased this about a year ago so I thought it was a good time to leave an accurate review.My problem: I have an aquarium in which I was manually dosing fertilizer and I wanted a way to automate itThis product was so cheap compared to others I thought it would be garbage in a few months but wow was I wrong in that assumption. It's been about a year now I think and it's been used every single day multiple times. I use one of the pumps to dose an accurate amount of fertilizer into the tank and then use another pump to top off the water that evaporates. I assumed because of how much water I pump into the tank on a daily the motor or something would give out but it has not. Very impressed and I would buy this all over again.The LCD menu is pretty easy to use, with no issues at all. Took me a few minutes to figure it out and from that point, after setting everything I just set it and forget it!Pro's-navigation very easy to use-cost vs other comparables-quiet-reliable-4 pumps in totalCons:-None, I cant even think of something to improveIf you have a use for it and your wondering then just buy it, I am very happy overall (happy enough to leave a review after a year)
