Well, I have been a bodyoptimise member for 20 months and have so far lost 6 stone. I love it as it is perfect for me.
I don't like classes and work away from home a lot so can log on any time and read the features, success stories, fill in my food diary, check syns, get a recipe, weigh in, update my bodymagic log, etc
I get an e-mail once a week telling me it's time to enter my weight and I have all my awards and a graph showing weight loss on my progress page. I can also upload monthly photos to see my progress over time.
It initially costs £60 for 3 months, you then get cheaper resubscription options of £40 for 3 months, or cheaper for longer. These fees have to be paid up front. (I like this because I feel it makes me stick to it otherwise I would be wasting my money)
I have never had a phone call from SW and there is no personal contact (I like this- lol), unless I choose to send them an e-mail asking a question. I get all the info as the changes happen, as long as I check the 'features' section on the site- they aren't pro-actively sent to me.
The real down side is that when I get to target, I will still have to pay for membership as there is no way of them proving that you are still in target (you could just lie to get free access)
I have always felt that I have the support I need using the on-line service, but can see how it isn't for everyone as you get no personal one-2-one help. Although I don't have a personal consultant, I am never given information which has been wrongly interpreted (as sometimes happen at classes- on here we see different views from different consultants) as my info comes straight from SW. If I have a good/bad week I just get a generic help feature to read and don't have an opportunity for someone to go through my food diarys
As others have said you can get many of these services on here or by getting the books or going it alone. This is like some people who think classes are unnecessary and can do it from home. Everyone is different- you really have to choose the option you think will work for you. Online membership really isn't for everyone
I hope I have given you a balanced viewpoint of the pros and cons- ask away if you have any further questions, as you are asking someone who actually uses it every day.
