Actually, laziness has a high price. A lot of people will ask - why spend the extra money for a power trash can? The simple answer is that it is more 'convenience' over function. I own 2 of these touchless trash cans. These are my recommendations: a) DO NOT get the round one. There is a analogous round trash can that is about 13 gallons as well - it also is iTouchless; but, there is a major difference. It is MUCH more difficult to get the trash bags out of the round one than the square one. The mouth on the square one is also much wider - allowing one to easily scrape off plates, etc. b) make sure to get the power adapter. I do not use batteries - but, run it off the AC adapter. This is an extra cost that you should budget. While the rechargeable batteries could be an option - I would think it is more of an annoyance than using the AC adapter; but, that is a matter of personal preference. Overall - is this something that a person 'must' have? No. It is a novelty item and a frivolous expense. However, for me, this frivolous expense is well worth it. All of us buy junk and regret making the purchase later on - I do not have any regrets with this purchase. Hope this helps.
