If it's something i got from here that I'm not expected to review I wait try it out for as long as it takes in everyway possible for me in order to get a better feel for the item & that takes time. I have to try out all the special features and claims on the item like waterproof, pure silicone, different functions and places to use it, etc.
Sometimes things I buy get discontinued as soon as after I purchase them so I don't get the chance review them. Other things I bought as gifts to others I will not review, and also toys I could not use for whatever reason or anything defective.
If it's review that Eden wants as in some type of assignment I will get to it as soon as I can and do it in parts, packaging photos and basic info when I first get it, and the rest after I have used it several times so I write it the best I can and be the most useful to readers.
Also it's less overwhelming to me to do a little bit here and there until I feel the review is perfect.
