What is the disadvantages of it
Hi @Ali_Alhosain if you use the search function at the top of the page you can find all the articles, posts and reviews that others have posted and find lots of useful information about products you are interested in.
The question you have left is a bit vague. People find lots of different things a disadvantage where others might find things no problem at all.
Have a quick read through and maybe ask a better question
Excellent advice there @Oggyboy
