Product review (5 stars): Love my Avanti
I didn't purchase this on Amazon but I do own it (for a week and half). It washes amazingly well! First please remember you are buying (or looking to buy) a small portable machine. This is not a standard washing machine so some things will be different.
A few things to help decide:
1 - I changed the hoses. The hose that it came with (2 hoses for hot/cold hook up) had plastic ends but the (male) part to connected to the sink was metal. If you are going to use the hose it came with, use plumbers tape around the sink to avoid stripping. (I didn't, hence replacing the hose). Also, they are not very long.
2 - Make sure it is placed on a flat, even, hard surface (as indicated in the instructions). If not, you will hear a lot of rattling. If you do, the machine is not any louder than a regular washer.
3- the spin cycle gets clothes super dry (which is important if you plan to hang the clothes and not use a dryer)
4- I haven't used a "large" load but it does hold a considerable amount.  Although I won't recommend over packing it.
5 - If you choose to use liquid detergent, I recommend just pouring it straight into the drum as the container for it doesn't hold the liquid very well. If you use powdered detergent, you can still pour it into the drum but it will definitely hold better in the dispenser. Also note, there is no place to put fabric softener but it's a portable (small) machine!
6 - Easy to move, however the wheels are very tiny and in the back so you would probably have to tilt it to use the wheels. I just simply slide mine across the tile floor. And no it hasn't scratched the tiles.
7- (probably should've started with this) - make sure you put in the noise plate at the bottom (screwdriver needed). I read a few comments complaining about the noise. If it's not on an even hard surface, then yes it will be loud. Also, if the noise plate isn't connected, yes it will be loud.
8- It recommends using a wrench but if you are connecting to a kitchen/bathroom sink, then hand tightening will be enough.
