I had the previous version that lasted at least 27 years. How I wish I bought 2 at the time. This one is similar, but there was nothing like the original. The knobs are bigger on top. My first one, the on and off switch broke, but I was still able to slide it. I hope this one is the same. I am trying to be careful, but with plastic, you never know. After my Original one broke for good, I had a temporary replacement that I hated. It was overly bright and did not have a Snooze button....No Snooze Button !!!....Forget it. I could not wait to get this one. It is not as Bright as the last one with no Snooze button, but I guess they are all that way now, brighter. But it is good for me because I can see the time without my glasses on. I miss the Original Alarm. This one is annoying with the different beeps, but, it gets me up eventually within 1/2 hour...does the job so far. It is well packaged with screw on feet attached to the box...amazing...I do hope it lasts a long time because it is very affordable and the last one was so reliable.
