Feature:
All the effects I expect plus a few I didn't. And the fact that this unit has USB audio is a tremendous advantage. This saves a lot of time configuring an external USB audio device that would had doubled the cost of the setup. Also I should mention that the USB audio, although not officially supported, works just fine with Linux. Another advantage...

Quality:
Metal case. overall one of the better units. Perfect for your irresponsible teenage son that smashes all his toys and expect new ones the next day.

Value:
As stated above, this is definitely worth every penny and more.

Desirability:
Not swayed be looks.

Sound:
I've been playing for over ten years and for the money this unit can't be beat. I doubt that any other manufacturer could do much better in this price range. More than adequate for home recording.

Ease of Use:
I haven't needed to read the manual yet.. That should say it all. Pretty slick arrangement of controls.

Support:
haven't needed it yet.

Overall:
This will inspire you to create. Get it.

Feature:
Downside to this pedal is no pedal, maybe you need one maybe you don't, I wish I would have bought one with the built in pedal for my style of playing. Upside, USB port(CABLE NOT INCLUDED) for direct recording, which is great when you have a riff idea or are working on something you don't want to forget...save it on a computer. Good for recording your rhythm track and then playing your lead over it.

Quality:
Well made. The DC power jack on mine is tight, no worries of it coming unplugged. No power off button, which sucks, I use a power surge strip to kill power.

Value:
Good for the money, enough settings to make playing guitar interesting. I would recomend this over other brands.

Desirability:
No sex appeal felt, maybe they should make the enclosure or case in the shape of a woman...then maybe...maybe

Sound:
Sound is good, lots of settings to choose from. Many settings sound the same or are so close they sound the same. Great for distortion, adding some fill in guitar sounds to tracks your recording.

Ease of Use:
Easy to use, I even used it with a mic to make sound weird sounds and voice changes.

Support:
Never needed to use support,

Overall:
Pretty good overall, I bought a couple for Christmas gifts, If your looking to play around with effect, other sounds, and have fun without buying lots of stand alone pedals, This is worth buying.

Feature:
I like the knob much better for fine tuning stuff.

Quality:
look all I really want to say if your even thinking of getting the older rp50 dont. this blows it away. In sound, in technology and most important to me it has a good sounding drum machine. Where the one on the old rp50 is a joke.

Value:
Pretty amazing for a benjie

Desirability:
If I was to get another maybe I would go for the higher end digitech but this is nice starter effects unit.

Sound:
I give it an 8 because its a decent modeler and a light year better than the RP50. I originally bought the rp50 and sent it back and got them to send me the RP150. Let me tell you its a keeper. I only give it an 8 because it doesnt quite capture the real deal but for 99 bucks it should be a 9+ IMO. I dont give out 10s easily.

Ease of Use:
just started using the computer editor seems pretty good so far

Support:
havent used the support yet

Overall:
pretty amazing what you can get for a hundred bucks. Is a pro going to gig with this probably not but your probably not a PRO. Its fun and for 90% of the people it will do the job.

Feature:
It's great for a large range of sounds. I also love the metal case, it makes it a little more durable.

Quality:
I guess it's pretty good, but the noise gate doesn't work on mine. It still can offer pretty good sounds without it, but it just isn't quite the same...

Value:
This is definitely worth the money, but I really don't think I would spend any more money on it than I did.

Desirability:
It looks alright, but the cover over the face of it started peeling off of mine. Now it has a ton of ugly air bubbles in it.

Sound:
This processor has some pretty awesome effects.

Ease of Use:
It's pretty easy to use, I only had to check the manual to figure a few things out, and it was pretty easy to understand.

Support:
I really haven't dealt with the service, but I have heard from my friend, who also has this product, that their service is pretty good.

Overall:
I think that this would be what I would stick with, unless I got the RP250 for the built in variation pedal it has.
