I almost didn't buy this due to some of the negative reviews but glad I took the risk. Though initially I did have some difficulty getting the app to connect to the device, once I overcame that I found the app and device worked perfectly. Calibration was easy enough and setting up a schedule also easy as is manual operation. To get the iPhone app to connect to the device I did end up having to disable Smart Connect on my Netgear router so that I could connect my iPhone specifically to the 2.4 ghz radio. But then after successfully getting the app to register the dosing pump I was able to re-enable Smart Connect on the router. Overall very happy the purchase thus far.

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.

Overall does its job than expensive ones in the market . Key points 1) Always calibrate with the amount close to your targeted dose. 2) Placement of the liquid source has an impact like height and how far its is if you change any of both re calibrate 3) Use AP network method for wifi connection mentioned in the user manual. 4) Always prime the pump before calibrating. It can be done via the manual pump switch on top of each pump. Priming means the tubing is filled with water . Cons I wish they log when teh dosing pump works . It can be done easily via an app chnage

I have been using this doser for over a year, and while it is still working I strongly recommend looking for other options. Pros 1. It works 2. Can connect via WiFi. 3. Can set schedules for each individual channel. Cons 1. WiFi setup is finicky. It is easier to connect to its built-in in WiFi channel during setup. Once configured, you can switch your phone back to your home network. No need to switch back to its built-in WiFi for any maintenance or manual use . 2. It loses calibration easily. if you were planning on using this for a Reef tank, so yourself a favor and look for a proven doser. You will easily ruin water parameters within a week or two. 3. "Normal" WiFi connectivities are a PITA even if you're router supports 2.4Ghz. It's just bad. ----------- All in all, it is an ok doser, but not recommended if the intended use requires very specific dosage that can't have the risk of over or under dosing.

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.

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.

I bought this unit to replace an older model Jebao that I had been using for over 5 years. This is definitely easier to use due to the app. The directions aren’t great, but the unit is simple enough that you can get it going with a little patience. Many people have complained about their inability to connect to wifi. I also had difficulty at first, but after simply pausing the 5.0 ghz signal on my wifi router, it connected to the 2.4 ghz on the next try. I have an Eero router which allowed me to simply pause the 5.0 signal for 15 minutes via their app. The Jebao app isn’t perfect, but simple enough if you follow the directions. I also had watched a couple of YouTube videos regarding the app and programming prior to purchase. I calibrated each pump individually and found there to be only slight variations from pump to pump. I plan to recheck calibration monthly just to make sure things stay close over time,and I’ll try to update this review with those results. UPDATE- after 2 months since my positive review the unit has now lost wifi signal 3 times and nearly crashed my system. I have fiber optic service that is extremely reliable. The signal is very strong so there is no excuse for it to lose the signal. I am going back to a non wifi based unit for peace of mind. I previously rated this 4*. Rating changes to a 1*. If you have a reef tank, consistency is what you’re after. You won’t get consistency out of this unit.

Seen a lot of negative reviews about this product. Seen where people were having issues with the app, setting up the WiFi, setting the dosing pump and calibration. I just came from a DP-4 Jebao doser, and I couldn’t be happier with this doser. Easy set up, WiFi was easy to install, calibration was easier than the dp-4, and setting up the schedule was so much easier than standing there and going through each fields to set up my 2 part, magnesium, and vodka dosing... it was so easy and for the cost I only hope it lasts longer than the dp-4. The dp-4 2nd pump would cause the 1st pump to go when it was activated. I’m sure it’s due to moisture getting on the circuit board causing it to make both pumps come on at the same time. The old doser still works on 1st, 3rd, and 4th pumps so I’m sure I can use it as a back up on something else. All in all I highly recommend this dosing pump. Time will tell how long it will last but for ease of operation this is definitely the way to go... Happy reefing!!!
