Round 1

Reviewer 1 Report

The authors have touched upon a very important aspect of quitting e cigarette. The manuscript is well written and conveys clear conclusion. There are a few points that I want to draw the attention of the authors

1. As described by authors this is a self reported quit attempt by the respondents and could not be verified

2. Some questions on users attitude - whether they consider e cigarette as/more/less harmful than conventional cigarette would be useful.

3. The sampling method could have been improved. The authors should attach a supplementary file of all the initial responses recieved and describe in more detail how they excluded some from it only. The methodology of exclusion can be explained in more detail.

Reviewer 2 Report

The authors surveyed those adults who ever used e-cigarettes regularly and had attempted to quit e-cigarette use by using Amazon Mechanical Turk. Based on the final 787 samples, the manuscript shows the frequencies and proportions of the demographic characteristics, e-cigarette/cigarette use, and device characteristics. It also analyzed the e-cigarette quit attempts reasons, methods, and experiences among all ever e-cig users. The survey design is meaningful for studying e-cig use and cessation. However, the literature review and background introduction can be improved by adding more US e-cig studies, and the results may have some problems. My 17 comments are attached. Please check.
