I have been using Gixen for about a year, and it didn't fail me even once. It is independent of my home network, so I don't need to worry if my PC is up, if internet connection is working, and I can change/cancel/check status of my bids I have set up anywhere, just by logging into Gixen website
Long time ago I bought AuctionSentry with the upgrades for life, when the company was sold and a new owner didn't honour that arrangement.
At the beginning I was a little sceptical about Gixen.com, I didn't like entering my password on unknown website. I did the research and everybody was talking just positive about it, so I decided to give it a try. There was not a single security problem and after a year I feel comfortable with Gixen using my eBay password on my behalf.
I would recommend it to anybody. Well done!!! 5 stars from me.
