The Joyo Vision Dual-Modulation is a modulation multi-effects pedal: 18 modulation effects in a single enclosure, any two of which can be used in isolation or in tandem. Premier Guitar's reviewer described it as "a treasure trove of tremolo, chorus, flange, and phase, and more radical modulation machines," from a maker "known for their inexpensive effects." Street price at the time of review was $901.
The 18 effects and the two-group layout
The effects are divided into two groups called "Mode A" and "Mode B." Each group has its own 9-point rotary switch to select an effect, dedicated depth/mix knobs, and separate speed/rate and control parameters1.
Each effect also has a "control" knob that changes function depending on the effect selected, so the same knob does a different job under a flanger than it does under a tremolo1.
Running two effects at once
The Vision's most prominent feature is a dual-footswitch design that enables parallel or in-series use of any two effects. A center-mounted toggle switches between series or parallel output, allowing you to cascade Mode A into Mode B or run the two side by side1.
"The center-mounted toggle enables you to switch between series or parallel output, allowing you to cascade Mode"
Both footswitches can also function as a tap tempo switch for their respective modes, activated by holding down the switch and tapping the desired tempo1.
Power, stereo I/O and what the reviewer said
The unit can only be powered with a 9V barrel adaptor, and there is no battery option1.
There is no battery option: the Vision runs only from a 9V barrel adaptor, so it needs a spot on a pedalboard power supply rather than running from a battery like some single pedals.
On the crown (top panel), there are stereo inputs and stereo outputs1.
Premier Guitar's verdict was favorable for the price point:
"Very inexpensive unit with a huge selection of effects. Tap tempo for both channels."
The reviewer also flagged one limitation: "Some players will probably long for the ability to create presets, given how many possible textures are on tap." There is no ability to create presets, so sounds are set by the knobs each session1.

Questions
Does the Joyo Vision take a battery?
No. According to Premier Guitar's review, the unit can only be powered with a 9V barrel adaptor and there is no battery option. Plan your pedalboard power accordingly, since a battery-powered setup is not possible with this pedal.
Can the Joyo Vision save presets?
No. Premier Guitar's reviewer noted that the Vision has no ability to create presets, and suggested that some players will probably long for that feature given how many possible textures are on tap. Settings are dialed in by hand each time you play.
Does the Joyo Vision have tap tempo?
Yes. Both footswitches can function as a tap tempo switch for their respective modes, activated by holding down the switch and tapping the desired tempo. Premier Guitar counted tap tempo for both channels among the pedal's pros.
Is the Joyo Vision stereo?
Yes. The pedal has stereo inputs and stereo outputs on its top panel, which makes it usable at the end of a stereo chain or with a stereo rig.
Can you run both effects in series on the Joyo Vision?
Yes. A center-mounted toggle lets you switch between series or parallel output, so you can cascade Mode A into Mode B or run the two effects alongside each other instead.
