Works great!
I purchased the same model 2 years ago and bought this one to replace it. It's currently attached to an 18k btu mini split air handler and works great. The newer model pump is smaller and much quieter than it's predecessor. My old one still works, it was just clogged, so now I have it as a backup.

In-line low profile sump. The only of its kind.
I use this pump to pump wastewater from my coco hydroponic grow setup. It is the lowest profile sump I have ever seen and works great. Setup is weird cause you have to wire the plug yourself but once that's done it's fire and forget. Note to purchasers - if you expect to have much pressure buildup be sure to attach the snorkel tube, and even use a longer snorkel tube. Failing to do that can allow for leaks. The purpose of this device is to drain slow drips off of a a/c condenser so it's no surprise the stock snorkel may be a bit short for other uses.

Small and powerful
Works great. The small size is the slightly negative issue for me (which may be a plus for many uses). This unit is in the attic and comes off of an Mini split AC unit to pump the condensation outside. It accomplishes that task very well, no problems. The hard part was mounting the unit so it stayed upright which required zip ties (which also worked well.) Since this is in a space that is hard to access a larger flatter unit would have been preferred just for peace of mind. Again this unit works great.

Buy this if your portable AC has a gravity-fed drainage valve barely an inch off the floor
Perfect little pump for making the drainage from my portable air conditioner a non-issue. The output was such that I had to drain it DAILY (the manufacturer and reviewers either lied, or have never been to Florida), which was a huge pain, but now I never have to think about it. Installation took about 10 minutes, leak-free with no additional parts besides an adaptor from my AC to the input tube. I can hear it when my home is silent and I'm within 2 yards of it, but even then, it's as brief and quiet as a considerate adult having a sip of water through a straw. Can't yet speak to its longevity, but you can't beat the price and convenience. This little gadget saved my summer!

Very quiet when the pump is running.
You may want more ¼" tube when you get this. Other than that, it is really quiet. Install is simple, plenty of videos online showing how to hook up if needed. The water flow works and you cannot hear it. The built in power shutoff is a nice feature. The pump will cut off communication from indoor and outdoor unit if the pump gets backed up. For extended durability, you may want to flush out the drain line which you can find how to do that online. Great value for the money!

Stopped working, need replacement but what a pain
Stopped working in 45 days. Possibly a single bad unit and getting a replacement is welcome but a pain to work through.

What a great product! Small and powerful!
It took me about an hour to install and worked perfectly! I was worried that the reservoir would be too big but it was just the right size to fit inside the front of the furnace out of the way and out of sight! I'm just over the moon with how well it works!
