Very usable
The octave becomes more apparent when you play higher notes or especially 12th fret or higher. This means you're able to play chords still and not have to turn it off to go from rhythm to lead. Now if you hit a chord hard you can hear it almost break up and do some cool, almost synth sounding stuff. Two note chords sound great with this especially root note and 4th together and do some tight percussive riffs. Naturally it's not a clean octave but that's the cool factor about it. I run it before my Fuzz Face and they are a match made in heaven.
Love this pedal.

Simple but effective
Super simple due to knobs but extremely versatile, best before dirt pedals near octave effects.
Nice pedal
I really like this pedal because it gives the guitar a funky distortion and theirs no nobs so just one setting and it sounds brilliant.

Expensive
It's expensive for something that's basically a dan armstrong green ringer mod with a 15 dollar circuit, but I like the design and it does what it's supposed to properly

In a Premier Guitar Rig Rundown, Jacob Tilley's RJM Mastermind was noted to include the EarthQuaker Devices Tentacle, indicating its use in his setup.
A core of Wolfe’s lead sound is an octave-up snarl– which comes from an EarthQuaker Devices Tentacle, running after the OCD.
In this EarthQuaker Devices interview she elaborates:
“I love fuzz. I’m just a big fan of fuzz. I think the Tentacle is probably my favorite pedal of all time. It’s so cool before any kind of drive; it just really brings out the top end and that amazing octave. I just love it,” she said.
“My core tone is an [Fulltone] OCD, but without the Tentacle it just doesn’t sound right to me. I think when I [first] put the Tentacle before it for the first time, I was like, Oh my god, I think that’s the sound. So that is just such an exciting combination for me,” Wolfe said.
The pedal was also mentioned in 2021 Premier Guitar interview.
In her spare time, Wolfe explores every pedal she can get her hands on and entertains herself by searching for the perfect combination for her signature sound. She's put together a "desert island board" comprised of three pedals: the EarthQuaker Devices Tentacle analog octave-up pedal, running into a Fulltone OCD, and an MXR Six Band EQ. "That's the sound that belongs to me," she says.
In this "Fuzz Off" by Earthquaker Devices from 2019 the Tentacle can be seen at 00:53 between the the Hoof and the Hoof Reaper.
