I've marked it 6 out of 10 because it's really very good for the money. It's not going to stand up against scopes at 5 or 6 times the price and will fail miserably against the multi-thousand pound scopes, but for a touch over a hundred quid you get a very reasonable product. You don't need to buy any extras because the eyepiece and the bag come with the scope. (You will need a tripod unless your hands are very steady!)
Put it this way: buy cheap, buy twice can be a good policy at times because not everyone knows whether carrying a scope and tripod is going to be too much hassle. Ebay is full of scopes that have hardly seen any use - I'd rather have a 100 scope in the attic than a 2000 one!
When I move to a better scope, I'll try to find an enthusiastic youngster to give this one to.
Note that the Bresser brand has now finished/faded/gone/disappeared but the range is available under the Barr and Stroud brand.
