ERNE can easily hold 150 Pickleballs but you can realistically fit 175 balls if you don't mind 1 or 2 potentially falling out of the hopper as the agitator rotates to feed balls to the throwing wheels. You can see ERNE's specifications here.

Yes, ERNE can use any standard Pickleballs.

At least two (2) simultaneously, depending on the drill being used and what is being worked on. ERNE only allows a single smartphone to be connected at a time so one person will need to be responsible for selecting drills and changing parameters.

Yes, all instructions are located on website (check them out here).

Do NOT use ERNE in a wet environment, do not stand in front of ERNE during operation (throwing balls). Immediately stop ERNE if a ball gets hit into the opening otherwise it might damage the throwing wheels or other components inside the machine. Don't try to hit balls into the opening cavity, we know it's appealing but you might cause damage.

ERNE can throw balls as slow as 10mph and as fast as 65mph. You can see ERNE's specifications here.

ERNE can feed balls as slow as 1 every 10 seconds and as fast as 1 ball a second. You can see ERNE's specifications here.

Oscillation is the ability to throw balls from left to right (sweep) and bottom to top (elevation). ERNE supports both types of oscillation.

The ERNE remote control has two buttons, one to start the machine the other to pause the machine. The is an alternative to using your phone to start and stop the machine.

Push the button on the top of the handle and lift to extend or push to collapse back into the machine. Only use the handle to move the machine, never to lift it.

The smartphone application will show the amount of charge left on your machine in the upper right hand side of the screen. The amount of green in the battery indicates how much charge is left.

The battery can last, depending on machine usage, up to 6 hours. We haven’t seen it last less than 3 hours driving it hard.

Recharging the battery to 90% will take about 4 hours. For 100% recharge, it will take about 6 hours.

Stealthy operation means that it isn’t obvious what direction a ball will be thrown. Our machine moves an internal yoke to change direction or height of the throw. The yoke is difficult to see making the direction and height of the next throw “stealthy”.

Yes, ERNE supports topspin, backspin and flat. The level of spin is controlled via the smartphone application by simply moving the appropriate slider. Read more here or see ERNE's specifications here.

ERNE Throwing wheels come in two types, high-density wheels ($90/paid) and lower density wheels ($45/paid). All machines shipped after October 15th have the high density wheels installed. The high density wheels are much better at resisting the residue buildup created by the harder plastic balls (Franklin, Dura, etc). The wheels can be cleaned by using duct tape wrapped around the wheel and then pulled off quickly, this only works if it is done frequently otherwise the residue will not come off. If you are using our ERNE balls then either type of wheel will work well because the ERNE balls do not deposit as much residue. Regardless it is always best to have a spare set of throwing wheels.Here are two videos for the wheel replacement process.

Your Finger. All controls are intuitive and require nothing more than your finger to make adjustments to parameters like ball speed, interval, spin, direction, elevation, etc. Click here for more details or here to see the smartphone software in action.

Yes. Typically you use the phone to setup the drill(s) then use the remote control to start and stop the drill. You can use the phone to start and stop the drill as well but the remote is much more small and convenient.

The ERNE supports 28 different court positions that you can direct a ball to, this makes setting up a specific shot extremely easy and fast.

No, the application and machine use BLE (Bluetooth Low Energy) for communications which does not require a wifi connection.

Yes, the ERNE can use either the internal (charged) battery or it can use AC power via the supplied transformer. The power button on the back of the ERNE tells the machine what power to use. When in the middle position the power button turns off the machine and allows for battery recharging (using the supplied charger).

See unpacking and charging the ERNE for the first time here

ERNE is primarily made of a combination of ABS plastic, high quality aluminum and steel.

No, you can charge the battery from any level of charge remaining.

We suggest you fully charge the battery then disconnect it. Don’t store the ERNE in a wet environment. Make sure the temperature range doesn’t go below 0°F or go above 120°F. Never store the ERNE in a vehicle that is closed up and directly in the sun, this can damage various components.

ERNE uses a microprocessor and special motors (stepper motors) to drive its oscillation features, these operate much more accurately and smoothly than traditional DC motors. Also, ERNE on moves the internal yoke to change direction of a throw whereas many other machine rotate the entire machine.

Not for an extended period of time, temperatures can reach well over 100°F in a closed up car or when exposed directly to the sun through the window(s). These temperatures can damage various components.

Yes, ERNE is able to fit in most vehicles, here is what ERNE looks like when in travel mode
