That is an awesome price. Insanely low. BUT. The lines are only 3 meters so 10 ft. Installation on any 2nd floor rooms may be an issue.

Insane as in that's the all time low or normal price? I somehow have never looked for mini splits on there but I'm in the market

For people that have this. Did you install it yourself? Do I also need additional tools to install it?

It actually went up a bit in price but now qualifies for a $40 off coupon so stays the same price. https://www.aliexpress.us/item/32...1f9688Note this is a higher seer model so I think most would consider it better

Does it make sense to buy a more expensive unit? Some of these cheap ones are just insanely cheap

It's a good deal and all, but if it's made in China the mounting bracket will likely be 12 in and not 16 in. Also the air handler line might be short. That was my experience at least, we made it work tho...not as easy as a Mr. Cool not even by half.

Guessing these are not great at heating in 20-30 degree winter temperatures?
