I must say that within the big picture, I have been satisfied with the quality of SD. I have been a customer for over 7 years. I've had many disappointments, though. One order of 100, when they didn't work, I found that half of the capsules were empty. Customer service said that my claim was ludicrous, but I had witnesses to my opening empty capsules on video. Customer service said they would refund me, but I could never order from them again (they gotcha over the barrel, so to speak). I let it slide because overall, the product was good. This last batch, as I have noticed with the last few orders, is waning/down on strength, as the price keeps going up?!? Gee, thanks!

Good product, but be forewarned, stuff happens. As strength decreases, I find myself looking at other options...

<p>I’ve ordered this product dozen of times and had no issues. Dependable /consistent product. Always gets the job done and meets my expectations</p>

I have been using stiff days for many years and the product has never let me down. The shipping issues I have experienced in the past seem to be getting much better. Even though the pricing is more than generic viagra, stiff days works better for me. I wish they would offer better discounts for larger quantities.

I paid for 2 day shipping. product arrived on time

I have been using this product for years now and the last few bottles (green pills) weren't working very well not sure why because they worked great before so I stopped buying them for about 6 month or so. I decided to give them another try and these pills (red/black) work great like they did when I first started buying them and they actually seem to work better. This is much better than viagra or cielas.
