Batteries last long and of course depends on how much u use it ( just like anything else in this world , duh ).. spending $20 for wall power is like adding a second gas tank on a Toyota PRIUS

The Blackstar FLY3 amp is not simply a great product for electric guitars, it is one of the most effective and useful products of any category I've experienced in my life.

Great product but DC adaptor that I bought with this product, which was recommended, isn't compatible.

no buzzing sounds).Amazon mistakenly offers a Planet Waves 9 volt adapter with this amp; the correct adapter is 5 volts and costs $19.99 and not $9.99, I purchased the latter from Amazon and can't use it with the Fly3.Overall a good product; however, Chinese workmanship and reliability is always questionable, otherwise this would be a 5 star.

Great product for its size, i would highly recommend to all musicians

For a microamp, this satellite speaker is a good value.

For playing at living room or bedroom level there is no better value

As an almost complete guitar noob with a very basic level of knowledge this squirt is a great little value for a newbie like me

Great little Amp, nice tone and value for an itty bitty box

The great value I get from these is due to the combination I can make for practice

The small size of this amp will not prepare you for its brilliant sound quality

Sound quality is great for a mini, much better than the minuscule size.

Made in China so the quality is mediocre; however, functionality is very good and the sound is substantive for such a small device

Sound quality and build quality is very good for such a small amp cabinet combo

I purchased this to use as a practice amp, it is amazing the quality of sound that you can get out of it

the delay is usable (not robotic sounding...) and it actually sounds and feels good

And they give us a very decent delay for less than $70!

The delay, drive all work great but should come with a power cord.

Awesome authentic tones and great delay at a very affordable price

With the delay set low it sounds more like reverb, crank it up and you have some digital delay giving excellent dynamic to what is a surprisingly good sounding amp.

The dirty channel lets you get some solid almost

High Gain on the clean channel will distort, giving you from a fuzz up to a good overdrive sound, AC/DC style.

The only downside to the a.p is the overdrive channel

-).I like playing with the Gain high on the clean channel because it has a nice gritty clean tone for a solid state amp

The clean channel's max volume is pretty low, but the gain channel makes up for it (the guitar's volume rolled back gives a good clean sound on the gin channel).Very happy with this little amp.

Nice tone plenty of volume and the delay really adds nice effect.

A little smaller than I expected but sounds great and has good effects

This little rig sounds amazing for its size and the effects are really cool too

Pro- completely portable, battery operated, sounds good, special effects that work (clean, overdrive, shape, delay with level and delay time), not a toy, output for headphone or recording

it has good overdrive and delay effects incorporated plus an auxiliar jack for your phone and backup tracks.

Good for a bedroom where volume is an issue

The tone knob is really cool, and the volume is perfect!

The volume is much louder than my Pignose was, where neighbors can easily hear it

For kicks I cranked up the volume and gain with the overdrive and they did work pretty well

Volume, tone, and overdrive are impressive for such a small package.

You won't get a totally realistic tube-amp lead tone from this unit, but the FLY3PAK is very useful as a practice amp or jamming with others in the living room; after an hour or so I really started missing my tube-based Mesa amp

A great little practice amp and the batteries seem to last forever.

Impressive sound for such small speakers, great practice amps for travel.

I use small, cheap wireless and a Ibanez Mikro for the perfect, cheap travel or portable practice

Best practice anywhere amp ever, can't say enough good things about its sound and value

I have played this amp for 3 or 4 nights now and the batteries that came with it are still going strong.

They recommend rechargeable batteries when not plugging it in

Great little amp that is battery operated, great for those on the move

LOUD!The stock batteries last hours!

It didn't clip while I bashed that low b

It has good features for the price and really sounds great for the size

The delay feature sounds incredible and the overdrive does the job

There are some key features that are missing that should be on an amp like this....like a chorus feature

I like the delay as well, a nice feature to help expand the range of sounds

Great features..gain knob and gain button plus volume & equalizer knobs, as well as digital delay.

This thing is incredibly powerful for its small size, and has some cool features to boot such as the EQ and reverb dials... definitely gives you a lot of room to play with the sound

Best practice anywhere amp ever, can't say enough good things about its sound and value

First of all, the FLY is an incredible amp, which you can see from the great reviews, but I'd like to point out that at $66 for the amp, 103 cabinet, and power supply, versus the regular $99 is the best thing going.

The delay feature works great with my lap-steel and dobro.... this thing is awsome

I completely agree with one of the other posters--This thing will probably only get more expensive once everyone catches on.
