The delivery was very quick. But this was the only positive. Some batteries were not working. I was lucky that I ordered more than I needed. The term was also not good. After describing the batteries should last about 10 days, at a stress of daily. 5 hours. The first batteries I had to replace after only 2 days. Total stopped only 5 batteries for 7 days at a 4-hour exposure time. So the batteries I can not recommend.
