after read all the positive review on this clock , and because it be make by Elgin , I decide to purchase it . the FIRST one we receive run 15 minute slow every 24 hour , so I go to the trouble of call , repackage and return it to Amazon for a replacement . the SECOND clock work perfectly for all of a month , and then just stop work all together . I think it have run the battery out because of the night glow feature -lrb- which we keep at the lowest setting -rrb- , so I change the battery but that be not the problem -- the clock be simply dead . I be incredibly disappoint . and due to the fact that I do not immediately write into Amazon to return the second clock , now I find that my `` return window '' have close and I can not get my money back . somehow that just do not sit well with I at all . obviously , this clock have problem . consequently , I vehemently recommend that you do NOT PURCHASE THIS clock . I wish we could use a cord clock , but we power go out often enough to make it impossible , which be why I choose a battery operate clock in the first place . this clock be not the victim of rough handling -lrb- on we end , anyway -rrb- , and be never knock off the nightstand or drop , etc. . it just sit there undisturbed until it arbitrarily stop work altogether . unhappy AMAZON customer .
