I've used the Dynamix UPSD1600 for many years, this is my second one
(The first one I bought still worked after replacing the batteries)

Pros:
Good strong batteries
Took a long time for the batteries to fail and need replacing
Power lasted over an hour when powering my gaming rig and ONT while we upgraded to a smart meter while using my first UPS

Cons:
No Battery Bypass when a battery fails and needs replacing.

I asked Dynamics about this and was told it was by design (due to the UPSD1600 being one of their low cost UPS's)

Have and will continue to buy these UPS's, however I will be keeping a closer eye on the batteries and keeping a spare set on hand

Very happy with it. Our small reception buildings entire electrical demand is small enough to pass through this product giving us a fully functioning office with lights, eftpos, computer, routers, powered Wifi antenna and phones throughout a 20min power cut.

good product. nice and quiet when on 240v, but high pitch squeal when battery is in use. great capacity and plug and play capability. good product. nice and quiet when on 240v, but high pitch squeal when battery is in use. great capacity and plug and play capability.

Pros:
Nice and quiet (no fans).
Good runtime for small server & network gear (around 100W total).
Email notification is nice when an "event" happens.

Cons:
Software is clunky Java based crap. It could really do with an overhaul & be laid out much nicer (tried both Mac OS Mojave 10.14 & Windows 10, both the exact same).
USB communication constantly drops (without reconnect). Not a computer hardware issue.
Unit stays quite warm when on mains power.
Noticeable buzzing from inverter when providing battery backup power.

Unfortunately, because of the software & USB issues, I have had to resort to using this as a "dumb" UPS, so therefore I can't automatically have the server shut down on a power outage event.

I have a PC, a serve and two expensive monitors. The mains power in my region (Auckland) keeps having "micro" outages and brownouts. The results were a blown monitor power supply and a server that powers off at least 4 times per week. After installing the Dynamix UPS, I have not had a single issue. I chose the 1600 model as this was rated at well over twice my power draw. So far (2months) I have been issue free. My only concern is the plugs at the rear of the unit are very hard to plug into. You need a lot of force to fully fit the plugs into. I have a PC, a serve and two expensive monitors. The mains power in my region (Auckland) keeps having "micro" outages and brownouts.

great UPS for the price and does the job nicely. great UPS for the price and does the job nicely.

Great value UPS, arrived thenext day, very easy to setup and have not had any issues with since we installed. Great value UPS, arrived thenext day, very easy to setup and have not had any issues with since we installed.

Haven't had a power cut yet to asses them properly but they appear to work well. Just have a strong electrical smell which is taking ages to go. Haven't had a power cut yet to asses them properly but they appear to work well. Just have a strong electrical smell which is taking ages to go.

Great product, does everything it says it will, well. Checked it out by turning the power off to the security cams and monitors it kept them running for quite some hours.

I find this an excellent product, easy to use and is totally silent so ideal for a home office scenario. I find this an excellent product, easy to use and is totally silent so ideal for a home office scenario.

The main selling point of this was the really long warranty and guarantee that offers protection to your sensitive hardware. I'm really impressed with the pricing vs battery capacity. It's also a rather solidly constructed UPS as opposed to some of the others I have used that have been little more than batteries with flimsy shells. One downside is some of the heat output, it does get a little toasty and I'm still nowhere near the max output on it.

Keeps my PC server running (no monitor) for 2 hours after the power is cut! Keeps my PC server running (no monitor) for 2 hours after the power is cut!
