For other future comments:

1. In the sales thread, TS stated that the photo by lens which means that the photo is not the photo of the lens. It is understandable if you don't understand that simple English but please stop mentioning about the photo.
2. Before everyone keep asking TS to refund because he is at fault, are you sure that the buyer did not intentionally do anything to the lens in the one month's period just because he don't want the lens anymore and need the money. He may denied it butwho knows the truth ? However, silverfire may also be the one that knew the condition of the lens but hiding the fact that he knew about the screws.
3. A reminder to all sellers and buyers, please check your used items to make sure that the items are still in a good condition before you all engaged in any sort of trades. This is to avoid this kind of dispute in the future. We won't know who is actually the one that is correct or wrong in this situation. Furthermore, this matter occurs after a month which made everything much more worse.
4. Stop mentioning the word 'safe trader' and 'demo set'. This both words has nothing to do with this dispute at all. Safe trader doesn't mean that tag is going to be there forever. Demo set is used set. As long as it is usable, I don't see the point of mentioning it. If you want a totally VIRGIN set like TS stated earlier, get a new one then. A used set is always not a VIRGIN set no matter how many people used it. I don't blame you if you don't understand it.

5. Stop arguing and wait for Apis to settle this dispute. At this moment, both sides are possibly wrong. Someone is lying or both of them are telling the truth. Simple as that. So stop arguing and chillax a little.

Why so rage my friend? I did not say that you are wrong. I am saying that some cases are like that where users intentionally spoiled their things to get back their money since they do not want the item anymore and need the money. Furthermore, I state clearly that you MIGHT be wrong and silverfire also MIGHT be the one that should be responsible. Plus my comment is not directed to you. It is directed to other forumers that want to comment on this thread to think carefully before blaming it all on either you or silverfire. If you did nothing wrong, there is no point raging on my comment which I said you MIGHT be wrong and if you are not wrong, why rage? Always make the wiser step. If you don't like my comment, then you can always choose to ignore it. Learn to control your temper

Relax bro. I no angry. Understand your feelings. Just want other forumers to stop blaming either you or silverfire before Apis clear the dispute. Patient
