Why do people keep 'watching' my items on ebay but never buy them?

[Maham]

well... 10-12 visitors is not a great number which lead to purchase. But you have few options to increase the probability of that:
1. Reduce your price ( in this case, you said you can't..that's ok)
2. Try putting some pictures of your product, pictures help others to know that they're buying( helps you ALOT since you said your products are electronic hardwares)
3. Try to sell trendy things as well( things that are sold and bought a lot via ebay) and increase your seller rating, it helps others to rely on you as a seller and trust you.
4. give as much information about the state of the product and explain its condition.
.... I can't think of anything more than these....
