Service worked perfectly. I needed to initially deposit (minimum of $5 just as OP mentioned) and had used credit/debit card (which tacks on a 10% fee, so be mindful). There are 4-5 other methods of payment (crypto, alipay, etc) that have different and/or no charge to use to reload, or "deposit".
I was able to use this successfully for Gmail (I used the listing with the star symbol since I can't find any documentation regarding the difference, but didn't wanna take a chance) it was a 50 cent difference, so the chance is negligible. I was also able to get YouTube sms verified.
The process was quick and easy. The CC option creates an invoice that you'll need to pay (all within the same 'payment method' page), along with immediate availability. The actual SMS page is a little confusing at first, but it's simple. You use it in order (aside from the top bar--which you learn is where the sms/number/verification will populate.) You first select Real or Virtual, then country, then you can either search or select from the list of services you need. There's also a "Show all Sites" button that produces all sites available in that country. I noticed (but didn't attempt) the "Other Website" button (for services that aren't listed, but I assume would work with any site).
The FAQ is a little skim. Doesn't contain much helpful information, aside from some good high level info, and some "verification" common questions. Again, I couldn't find anything in that FAQ (or anywhere on the site for that matter) regarding the difference between the two (star/no star) website service listings, so I hope they add that in soon for people like me to understand.
The process of receiving the sms code was very quick. Code populated in less than 14-30 seconds, for both YouTube and Gmail, respectively. I like that they streamline their UI delivery of the code by populating JUST the number of the sms message, BUT you also have the option to "expand" the sms in the same line, so that you can confirm there's no other info required on your part. For example, the Gmail code (G-####) only populated as #####, which is fine, but I had expanded to confirm, that that was also populated and parsed correctly after the G-.
All in all, I would recommend the service. It seems fairly simple and quick, along with expected, for the prices. *I was not reimbursed nor asked to leave a review for this service, but I was first commenter on this sales thread, so I felt it necessary. Haha. GLWS!
