What's the difference between this machine and the one that sells for over $200 in Amazon?

I have the 7000 unit and have worked with this one. Both are great. A good unit should not cost at max more than $60 if it has a few extra accessories.

What size are the lead wire connectors, the pieces that connect the 2 sets of wires together? Its usually in mm?

I searched the pamphlet that came with the TENS unit, but I could not find the measurement. I am a nurse and see that the wire end is 1 mm and the electrode lead receiver is 4mm.

How much Amperage power does it have?

Pulse Amplitude: Adjustable, 0-100 mA peak into 500 ohm load •Wave Form: Asymmetrical Bi-Phasic Square Pulse •Size: 10.1cm(L) x 6.1cm(W) x 2.45cm(H) •Weight: 150 grams with battery. •Pulse Rate: Adjustable, from 2 to 150 Hz, 1Hz/Step •Pulse Width: Adjustable, from 50 to 300 microseconds, 10μs/step •Modes: B(Burst), N(Normal), M(Modulation), SD1(Strength Duration), SD2, P(P1-12) •Timer: Adjustable, from 5 to 60 minutes or Continuous.

I have to wear the tens unit in the gym. Is this tens unit smaller enough to put in your pocket or a bag around your waist?

Hello, thank you for your questions and the device dim. 2.4x4x1 it should be fit your pocket or bag. I hope you enjoy this device in the gym:)
