Like others, I was charged for and sent more than I ordered. Even though I contacted them immediately, a slow two-step process ended up claiming it was already being shipped. They tout a 30-day “Satisfaction Guarantee,” but the only guarantee is that there are many barriers to a return, and if you’re not satisfied there will be NO SATISFACTION.a) the product must be “unused”, “in manufacturer’s condition”, and “in its original packaging.” In other words, if you try it, you can’t return it. b) If you don’t try it, you can return it, but probably won’t. You have to get a “return code and return address” from them and that takes a long time. But then you find out YOU HAVE TO SEND IT TO VILNIUS, LITHUANIA! The cost to return the items is more than the original cost minus their 15% “restocking fee.” In short, they shout “30-day Satisfaction Guarantee,” but if you try it, you can’t return it. To return it if you don’t open the package may cost you more than what you would get back.An Unscrupulous SCAM – Never Buy Anything From Derila!BTW, Order # was 7K2EEM. You know my email address. And, I know exactly what your reply will be, exactly the same as for every other negative review below.
