Jebao Doser 3.4 WiFi 4-Channel Auto Dosing Pump for Saltwater Reef Aquarium, White (Doser3.4)

I don’t regret this purchase at all. I had no issues with setup and got up and running in just a few minutes. If you’re having issues it’s probably your router- this only operates on 2.4ghz so it might require some router settings changes to initially set up but it worked fine with my ASUS 86U. I love that I can adjust dosing from anywhere in the world now.I can’t speak to how it holds calibration over time, but I’ve used a non-WiFi Jaebo doser for years without issues. What I will say is that you shouldn’t be dosing anything you’re not measuring anyway. So in that regard, if you dose “5ml” and after a few months the calibration is off and you’re dosing 7ml….so what? You’re always going to be dosing “more” or “less” based on testing results, so the actual number doesn’t matter. With the non WiFi version some suggested calibrating 2:1 instead of 1:1, so keep in mind that’s an option if you’re having issues.Finally, the app. It’s very plain, but I don’t think that’s an issue. Keeping the code simple is sound engineering. I have my issues- it’s a little too easy to completely turn the doser off, and a little too easy to turn a pump on continuously. But otherwise the programming is straightforward and not an issue. The one thing that threw me for a loop; you have to hold-press on the doser to enter settings.~$70 for 4 dosing pumps vs. $350 for 2 Neptune pumps. Don’t get me wrong, I have Neptune DOS pumps and auto-adjusting dosing is great, but the value proposition in this item is just astronomical.

The media could not be loaded. 1. All 4 heads were squeaky from day 1. I replaced one of the heads with a spare one that was in the box, and it squeaks as well. Then I replaced one of the heads with a head from an older dosing pump, and that one doesn't squeak.2. Wifi configuration is not guaranteed to succeed. Access point mode didn't work without any explanation. As for the other mode , my Nest wifi mesh doesn't support explicit configuration 2.4 vs 5ghz, so I had to turn off the nearest router and hope that phone connection to the other one would use 2.4. Eventually I succeeded, but you can't be sure it will work for you too.3. The UI is pretty terrible. It's counter-intuitive, you need to tap and hold elements, and there are no Save buttons in many places. You just configure something and then tap Back and hope that the changes were saved.4. All of the previous issues fade in the light of this one. The pump randomly screws its config. Sometimes you turn off the program on one of the heads and in a few days find out that it's back on. Currently the app doesn't allow me to disable the program at all, watch the video. It's basically dangerous to use this pump for a reef tank dosing.Conclusion: even though I've happily used 2 other Jebao dosers for years, I consider this wifi 3.4 model a complete junk. The mechanics of the dosing heads, the app design, the wifi hardware and the cloud backend software - all aspects of this product deserve 1 star out of 5.It's going back to the seller.

This has made my life sooo much easier with my reef tank dosing. All you have to do is calibrate it and set it up for the times and volume you want and it takes care of the rest. The instructions are not great so make sure you set the "Day Interval" at 0 if you want it to dose every day. Set it to 1 of you want every other day. 2 for every 2 day, etc.Only improvement I could suggest is better instructions and and some kind of level monitoring for the bottles, but for me this is not a big deal. It's great on it's own and even better at its price point.

After reading many reviews with mixed results, I decided to order two of these dosing units. I wanted a back up just in case the primary failed but I also wanted more than one because I read people had issues with the Wi-Fi.Unfortunately, I was one of the people that had issues with the Wi-Fi. The first unit I tried and tried with multiple devices in multiple networks and had no success.When I opened up the second unit that I ordered as a back up, I easily synchronized it to Wi-Fi. I was unable to do so using my iPhone, but I I had success using my iPad.I’m not sure why one worked and The other didn’t, but if you are one of the people who is having trouble try using a different device to connect. Once it is synchronize with Wi-Fi, you can use the app from any device and it will appear.As for the performance, these work the same as pretty much every other doser out there. Another complaint that I commonly hear is that these are not very accurate. I will vouch for this, over a period of 60 to 90 days they can become someone in accurate. This is easy to correct if you re-calibrate them regularly. For me it’s worth the effort because they are such a bargain compared to the more expensive units. Even the more expensive units need to be recalibrated to ensure accuracy.I think this unit is a great value for the money, just be prepared to Return the unit that doesn’t work with your Wi-Fi or order multiple at one time as I did.

It worked great until it didn't. The app connection on both of my iphones failed and it would take a couple resets of the doser and the app to get it working again. But today, nothing is working.Would you believe, yesterday the return window closed.I was about to return the item, and ask for a replacement as I like the product. But alas.If someone from Jebao is reading this. Please make a plan to send me another product and I will re-rate your product.But if nothing happens - I will not edit this review - so other buyers, buy at your own risk.
