Hi all,
Here's my brief experience of the purchase. I am from Singapore and here's my delivery tracking breakdown:
4th Dec (Sat @ 3am!) - Placed order and made payment via Paypal
5th Dec - In transit (to HK airport)
6th Dec - Left airport en route to Singapore
7th Dec - Arrived in Singapore
8th Dec - Package arrived at my doorstep
Very fast considering the order was made in wee hours on a weekend. Technically took 3.5 days to arrive.
My brief review of the product
I ordered the 3 pump version and as per shifty51008's images, the package was well wrapped with the individual components packed seperately.
On the whole, the unit worked well and the I was able to get rather consistent pump rates (10ml per 16 seconds at fastest pump rate). However, I have only tested a few hours then as my (freshwater) tank will not be ready until a few weeks later. I noticed a couple of things which may be useful to others when I first opened the package:
First thing I noticed was, all 3 timers were still active without power. I pressed some of the settings and the 3rd pump timer display faded off. I rectified this by plugging in the provided adapter (220-240V for South Asia) and the timer became lit again. I attributed this to the lack of stored power rather than a faulty part.
Another thing I noticed was, one of the 6 display light nodes was extremely dim. Upon closer inspection, I noticed that the bulb had collapsed into the cavity. I opened up the main unit and pushed it back into the socket - this was when I noticed the rest were fairly loose. They were held up by the sheer grip of the bulb against the socket and came off easily. I used a tiny bit of super glue to hold them in place.
The internals of the main box unit was messy and most parts were held together with hot-melt glue. The tiny circuit boards were either loose or had lots of freeplay and would rattle when the unit was turned about/upside. This had no impact (fortunately) on it's performance.
The pump heads looked well built enough and were really quiet without any backpressure into a container level with the pump unit. I had to literally touch the pump head to confirm that it's pumping.
I also tested the output with an enclosed in-line CO2 reactor (high backpressure) and the liquid managed to flow without any issues. It was however noiser due to the flow resistance. It sounded like plastic flexing/clicking especially at lower speeds where there's lack of rotational continuity due to 'start-stop' sequence of pumping.
Timer controls
I am very impressed with the level of customisations I can have. There are more than 20 seperate time slots you can set per timer. The smallest unit is 1 second. You have basically 2 modes so you can only use either mode but not both.
1) Start time (Day(s) HH:MM) -> Stop time (Day HH:MM)
2) Start time (Day(s) HH:MM) -> Running time (0-59 seconds) after which it stops
(1) is more suitable for a variable duration dosing, e,g (5 mins in morning, 10mins at night)
(2) is more suitable for precise quantity dosing (e.g. pump 5 times a day @ 10ml per dose)
Hope this helps!
