Bests & Worsts Reviews from Amazon

I purchased the 18 in Neewer Ring light for my lash extension business I've currently own a 14-inch one so I thought having a larger one would be perfect however this is literally a replacement light for the first one that I purchased from this company or seller this one doesn't even work at all it will turn on it flickers on and off but it's not stable at all where the light remains on it always shuts off and on I've check the chords I've reached out to Amazon and I've also reached out to the seller haven't got any response back yet and I literally can't even use it
