Worked for 4 months and could not find an authorized dealer to repair it less than 300 miles away.

I have an older model (PAC10) which is nothing I would recommend. It is huge although is called portable (it looks slim only from certain angle used in pictures) and was just very expensive for what it is. It is almost as noisy as window AC. If you really want European standard AC, that is quiet; energy efficient and does not need window or duct work, I would advise to check "mini split ductless" type of AC/Heat Pump (these need technician to install them though).
The reason I write here is that at certain point you will need to buy parts or accessories from DeLonghi authorized provider in the USA, Fox International. This is the worst possible (unimaginable) service that you may get. I have placed an order 1 month ago and my order status is still "processing, check in 24 hours". Knowing that spare parts will be needed not too long after purchase, I strongly recommend choosing another brand.

Overall, I am very pleased with this unit. Easy to install and works great! Would recommend this to someone who needs a portable ac.

I would only buy this over a window AC unit if you value the portability. It is quite heavy, but is on wheels so it is portable. AC unit cools well. Window insert is poorly designed, so you need to use putty or something else to modify the fit in the window sill to prevent the flow of warm outdoor air into the room.

This air conditioner definitely does what it says it does. It cools very quickly and is fairly compact. Pretty powerful for the size. Simple and easy to set up.
The first unit that arrived was damaged during transit. This is the only real downfall in ordering this machine from Amazon. The air conditioner is shipped in the same box that you would get it in if you purchased this from a brick and mortar store. So, if the shipping people decide to drop it, the unit stands a very good chance of being damaged.

I did have to return the first air conditioner. Amazon was very quick to replace it. The second one arrived without any damage whatsoever.

Both units were brand new. They weren't refurbs nor were they returns.

The only reason that I didn't give this 5 stars is the shipping damage issue though that has nothing to do with this product's performance. But we were in the middle of a massive heat wave, my house air conditioner broke (!) over Labor Day weekend and waiting a couple more days for a working unit was agonizing. (yes, we are still waiting for the repairperson to fix our home ac.)

All in all, I'm quite pleased with my purchase and yes, I would recommend this product!
