80dB Seek-Help Panic Alarm Keychain (1*23A Included/Color Assorted)

Pros: It's small and light , easy to carry. It comes with many color, but i think u cannot choose when u order. The sound level is better than expected. It was not loud when u first pull the chain, but it will get louder in about 2 seconds. Not sure if it is indeed 80db, but it is loud enough for me.

Cons: I tested the item when it arrived. Pulled the chain, then the alarm went off. The sound level went to a maximum after about two or three seconds. I stopped it after about eight to ten seconds. After 17 days, i wanted to test it again, but this time, nothing happened. It is totally dead. I know it is battery operated, but i assume the battery inside should last longer than that. The quality of this product is totally unacceptable. It is just a waste of my time and money. I ordered several times from DX and all other items i received were quite good. This is the first time i had problem with my order. I already contacted DX about this, and i am still waiting for their reply.

Other: Though price is cheap enough, but i think i need a better product than this.
