Is this a good shutter release?

I want to get one for when I start using my tripod in the spring, especially when I do 4th of July fireworks with long exposures, but have no clue what to look for. Above is one I found, I want to buy it together with the reversing ring so if you see a better one on Amazon or Adorama please let me know I will be ordering from both tomorrow

nothing like planning early eh? haha that's good thing, but my friend has it, I used it a couple times, it works great and clicks on so you can leave it in bulb mode. does the job great, especially for 15 bucks
