Works easily and saves you money
Easy to use and will save you from having to pay someone else to do your Rv. I bought two and gave one to my daughter for her trailer

Hoses need to be straight out of box to work best.
Works great

Did the job
Worked great to winterize my RV. However, the smaller hose leaked and there was no way to tighten the hose to keep it from leaking. But it did the job and I'm happy with it.

Comes with the wrong threads on the brass fitting
RV water connections are designed for fittings that use 3/4" GHT fittings. This comes with a 3/4" NPT fitting that, best case won't screw into the fitting to form a seal or, worst case will chew the threads in the camper fitting up so that it becomes unusable and will need to go in the shop for replacement. This being advertised for winterizing RV's, one would assume it comes with the correct fitting to do the job. It does not. Couldn't use it this year, will find the correct fitting online or at hardware store so I can use it next fall.

Poor packaging and problem parts
The hoses were folded and badly crimped. The instructions said fitting should go on small hose but one I got would only work on large hose. The fitting did not tighten in the water hose inlet of my pressure washer. The pump is probably ok but would have to replace hoses and maybe fitting to make this useful. I return it

Shallow threads and short hose
Works, but the shallow threading on the end cause a lot to leak. It’s a small pump, so it’s easy to use even when holding the antifreeze jug. Tube could use an extra foot or so of tubing to make the process easier for you. It’s mostly plastic in build, but only using once a year, I can see it lasting for a long time. This is my second year using it

Great as a general hand pump!
I bought this as just a liquid transfer pump, and from that perspective - it's perfect at this price point. For the RV folks - I saw that fitting in the box and felt bad for you all. _THAT_ doesn't fit what you're looking for. Ugh. Regarding the bent tubes - yeah, they certainly chose cheaper tubing to go with the packaging solution. But - letting them sit in hot water for a while will soften them up. They'll smooth out straight with a bit of convincing. I wouldn't recommend a heat gun/hair dryer - they'll get too hot-too fast and you won't have control. Overall - recommended!

Made an adapter to connect to an in floor heat system to pump some detergent into the boiler. Worked great. I used a more robust clamp on the output, but the suction side was fine just inserting the tube into it. Used it to flush out the boiler and refill, and worked like a charm. A nice tool to add to the collection.

Easy to assemble and use. Perfect for wintering RV trailer and the tank flush port.

I should have read the reviews before getting this. As others have noted the fitting for the trailer connect is the WRONG thread and because it is brass it will damage your plastic RV fitting. I didn't realize this until after I tried using it and it spewed antifreeze all over the place. It comes with a large roll of teflon tape and that is supposed to seal the threads. DO NOT buy this.
