I am liking the Drop immensely myself. I was put off by the o-ring issue but Digiflavor (GeekVape) has sent me new o-rings, customer support from them has been good so we will see when the new o-rings arrive what my final rating of the Drop will be. Don't get me wrong I'll still think it is a great RDA and use it but will have to deduct a few percentage points. If the new o-rings fix the issue I am having of course I will add points and my personal rating will be even higher.
The Drop and Cosmonaut are my two RDA's and I am liking them both. The Drop is easy to install coils and wick, the Cosmonaut is super easy to install coils, wicking is a challenge , not hard different and I am looking for that perfect wicking technique. I only have had it since Tuesday.
Both RDA's provide outstanding flavor and cloud production. Airflow is nice on both, I think the airflow on the Drop is a bit smoother but that is my opinion. Someone else could believe that the Cosmonaut's airflow is better. Don't get me wrong, I'm still saying both are great RDA's.
I'm thinking about getting a Goon but my problem is I only have 3 mods and with the Kylin tank, the Drop and the Cosmonaut do I really need another RDA and mod? First world problems I guess.
