The SKS Topcage is pretty typical example of the sort of bottle cages available at this price, it's fairly light and holds on to your bottle well - the only problem I had was getting the bottle in there in the first place.
The plastic construction of the Topcage keeps the overall weight down and doesn't mark bottles either which can be a problem with metal bottle cages. It also comes with a small nose piece which can be slid forwards or backwards to accommodate different bottle shapes. Whilst a good idea in theory, in practise there wasn't enough rearwards adjustment available to fully enclose my generically shaped 600ml bottle. As such, the nose piece could well have been integrated into the bottle cage, reducing weight and the number of parts.
Ideally, a bottle cage should allow easy bottle entry whilst preventing bottle ejection over rough ground. To start with, I found slotting my bottles into the Topcage to be quite fiddly but I reasoned that things would improve with time and practice...only they haven't. I still find myself having to look down having wiggled my bottle around in vain for a good few seconds, searching for a way in. I attribute this to the high 'wings' on the bottle cage which jut forwards and often contact the bottom of my bottle first, deflecting the bottle away instead of guiding it in.
In terms of bottle retention, the Topcage performs well. I used the Topcage off-road on many occasions without mishap, but if anything, the problems with entry are exacerbated when being bounced around over roots and rocks.
Weight wise, the Topcage comes in at a claimed 53g which is about right for a plastic cage at this price. To be honest though, if weight is a consideration, you should be looking at carbon fibre models and be prepared to spend an awful lot more.
All in all, I was pretty disappointed with this offering from SKS. Whilst weight and bottle retention were OK, the design just doesn't enable intuitive bottle entry rendering it extremely frustrating to use.

Full plastic construction
Very difficult to get a bottle into
