Compare remote power and listed range
Check what powers both parts and how the listing describes distance.
List the device and controller separately
Overdrive lists a cable for both parts. The Fetish Fantasy kit mentions device charging without naming the remote battery. If one part uses a replaceable battery, confirm the type and whether it is included.
Use the distance as a listing figure
Pegasus and Angle Master each list up to 30 feet. Overdrive lists 32.75 feet. Those statements provide no shared test conditions. Check the exact manual and try the controls at a short distance before relying on them farther away.
