Power
How much power can the sex machine of your dreams churn out? Most devices have powerful motors that’ll power your dildo’s up and down movements all night. However, the power varies from one model to the other.
And for thrusters, a difference in the motor’s power might mean an underwhelming impact, especially if you plan on using massive fantasy dildos for attachments. So, consider your sex machine’s thrusting power in relation to your preferred attachments.
