100% effective or free

Far beyond legal obligation we prepared the guarantee of "100% effective or free" for our customers, which applies to all orders at our official eshop www.STkill.cz.

If you are not satisfied and STkill purchased from www.stkill.cz does not help to solve your problem, please return the product to our logistics center---ELMS service s.r.o. / BIORG, Budova B6, Ve žlíbku 1800/77, 193 00 Praha 9 - Horní Počernice, tel. 724 546 526 (only for the needs of the carrier)---within 30 days of purchase to recieve a full refund. Please also send us a short message to info@streptokill.cz, so that we can match your return shipment with your order.

Many of our customers buy 3 packs of STkill in order to take advantage of our buy-2-get-1-free promotion. This promotion is also covered by the guarantee of "100% effective or free", but please note that only 1 of the 3 returned packs, should you return them, may be unsealed or partially-used. The other Streptokills must be unsealed;  the 100% money-back guarantee applies to no more than one unsealed pack.

From our experience, STkill helps the vast majority of people and fewer than 1% of our customers have use the return-policy guarantee. We firmly believe that you will join the 99% of patients for whom STkill yielded significant results, and we look forward to having you among our satisfied customers.
