Q: What is the power consumption of this unit over a week of continuous use? (in usa on 110v). thank you.

This takes .3 Amps, so (watts = amps x volts) OR watts = .3 x 110 which equals33 watts. Now for one week would equal 33 watts x 7 days x 24 hours =5544 watts or 5.54 kilowatts for one week.At $.16 per kilowatt it comes to $.89 per week.

Q: What the difference between this and the starter kit?

There are two main differences:The Hobby Rock Tumbler has a rubber tumbling barrel with a stainless steel cap, which reduces noise and is more durable. The Starter Kit Rock Tumbler has a plastic barrel. The Hobby Rock Tumbler also has a keypad for setting the number of days you would like it to tumble, where as the Starter Kit Rock Tumbler's setting options are on/off. Thank you for your inquiry.

Q: What pound tumbler is this product?

Dearest National Geographic.... why would you only send 1# of rocks with a two pound tumbler?

Q: Can i buy extra grit without the rocks. we have many rocks from "mining" gemstones that i would love to polish. what do you recommend?

I recommend you follow the rock tumbler hobbiest MIchigan Rocks on Youtube. He's a good wealth of information for anyone getting into rock tumblers. He and other's mention that the polish from National Geographic is not good. I would go with rock tumbler polish offered by Polly Plastics.
