Feature:
Cant say enough. If you cant find something you like here than give up.

Quality:
Always top notch from Roland

Desirability:
Total sex. I used it playing out and several pretty girls came up and asked where I got the cute little amp.

Sound:
Sound wise its really really nice. I use it for acoustic guitar with a mc in the mic setting. Also use the same mic for vocals at the same time. I did plug a Strat into it to see what it did. It is amazing. You really get a vast variety of amazing sounds, and loud sounds if you crank it. The drum machine is total fun and useful. It has a volume control which is very nice. If you jam with players that tend to speed up this will keep the group straight. LOL. Tilting the amp back makes a big difference in getting the sound out.

Ease of Use:
Great

Support:
Never had a Roland or Boss product go down.

Feature:
Liked the tuner! STILL - Roland, why is there no external control to turn the f/x on/off? I've accepted the fact that you give us hardly any control over the f/x, but it would be nice to stomp the f/x or delay/reverb on/off as needed during a tune. The stereo chorus sounded VERY NICE!

Quality:
Never had a Roland product take a crap on me. This one seemed as sturdy as all the other Roland products I've owned.

Value:
Could've been a HUGE winner for ROland, what with promise of sounding like it's little brother, only louder and with a tuner. Sadly, it's "newly designed" speakers don't do this amp any justice, and produce a sad, boomy/middy mess.

Desirability:
It's being returned...

Sound:
Wow, I was really disappointed with the micro cube RX.. like the review before mine, I was and am a big fan of the original 2 1/2 watt micro cube. I really wanted a built in tuner and a little more volume, so the MC RX seemed like the ticket. Uhhhh, no, it was returned. It was very hard to dial in a sound that sounded as good as the original MC. The acoustic setting in the new RX sounded little more than a Roland JC clone, not at all acoustic like the original MC. The JC120 did sound fantastic on the RX, as did the mid-dirt channels. However the higher gain models only sounded good at low volumes. Punch the volume up (and there is a most noticeable boost in the amount of volume available) and the tones fall apart, and take a "boomy" and plastic quality. Another problem I had was with the EQ. Almost all of the models required the treble control to be 100%. To eliminate the boomy mud in the mids, the middle control had to really be cut back, and in a lot of cases, so did the bass control. Yuch! Very very hard to dial in a usable sound on just about any model.

Ease of Use:
Hard to argue with the ease of use... easy to use as a toaster.

Support:

HORRIBLE!!! i had the original 2.5 watt micro cube, the best $125 money can buy, loved it to death!!! then i upgraded to the RX for the wattage increase and found out they RUINED the modeling settings to the point where after months of trying to get it to sound like the original micro cube i realize it is not going to happen. the engineers at Roland took the best product on the market and RUINED IT! stick with the 2.5 watt original until Roland gets their heads out of their butts!!
