Sildenafil 20mg tablets worked fine for me, but I have 2 complaints. Firstly, the website is deceptive and sets up a recurring charge without telling you. Their CS did cancel once I realized and contacted them. Secondly, my Scam emails have gone from zero to 40+ per day since I created the account. CS claims they don’t sell email addresses to scammers, but I don’t buy it. Given the timing and subject matter of the scam emails, it’s too much of a coincidence.
