I use ensipe on Harrah's / "better chips" because:

It takes the personal nature out of bidding...
I usually place my ensipe bid early for my max bid, and rarely check the auction or change my bid. That way I won't see who is bidding, or impulsively raise my bid.

I am too busy and too lazy to sit at computer and hit refresh until the auction ends.

I don't forget to bid "later"

I don't alert other collectors to special finds I really want

It reduces people using me as their search engine and I don't have to ask my sister to buy my chips anymore

It's a tool - available to all - I find it quick, easy and affordable
