Yes, some info would be great, as yet we are not physic's on here, but are working on it. 
If you are considering buying, then look at their feedback, that's what we all have to do. As for asking other's opinions, well, we all have some issues with sellers from time to time, some great sellers have small issues, some bad sellers have big issues, but you have more of a chance getting a good result from a good seller who has say 100% feedback than one with a big issue and only say 97%. If you have purchased and the item is faulty, then first approach is surely to the seller, if you have purchased and the item is good, then you don't even need to tell us, as their feedback left by yourself should be enough advertising.
