This is a decent product for the price. The appearance looks more like glass than rock crystals, and does not have much color variation as seen in most flourite, but it is still pretty and a fun item. I have not tried the timer function as these were purchased as gifts.Very pretty! Also a little weighty so make sure if you’re going to hang them your hanging method can handle that. I’m using command hooks. The different flash modes are nice but the remote is REALLY REALLY difficult to use. I’m not sure if it’s all of them or just the one I got. I have to jam my finger into the buttons to get it to turn on or off or to change light modes.These lights were definitely a great purchase to help brighten up my study area!it's not as pictued. instead of blue fluorite as advertised its half green flourite have purple. not what I wanted at all... ?Stopped working ?These lights are absolutely gorgeous. Couldn't fault the glow, brightness, beauty of them. Create a lovely soothing atmosphere.Great to have a remote control with them. Number of buttons on it is excessive though.Nice to have lots of brightness levels to play with and good to have different settings e.g. fading / flashing /always on/random etc. I tend to stick with one setting that works nicely for me.Timer function is great except limited to either 2 hours or 6. Would prefer if there were a 3 or 4hr option.They seem to eat batteries. Take 3 AA batteries and they don't last long, constantly having to replace them even though the lights are only on 2 hours a day. Tend to leave a few days break between.Overall would recommend these lights. Love that they're a natural material too.Firstly, it's nice to have lights that aren't plastic. These fluorite lights are much nicer. Secondly, the colour is beautiful, eerie, like a fantasy scene.Only downside is the metal wire. The fluorite pieces are heavy, so I'm worried they may snap the wire- it is pretty thin.Also, at night, wrapped around the arch it kind of looks like I opened a portal to another dimension, so... be warned. Just sayin'. ? ?Omgosh these are lush! If you're considering buy lights for your bedroom or teenagers bedroom or any room? GET THESE!! Yes they are blue. No they don't look cold. They look warm and glowwy(is glowwy a word?!).Beautiful turquoise blue colour to the led's, would be suitable for a boy's bedroom as well as a girl's. Lots of different modes to play with, dimmable too. The chunks of fluorite are quite sizeable too, though they do vary in colour. Some are greenish, some have purple, etc.I never leave reviews on here but needed to for these. I was expecting tiny fluorite chips but these are about an inch long each, making it quite heavy so need to be careful when hanging them, but they are absolutely beautiful. They have a function button on the battery pack but different functions if using the little remote control. They are definitely worth the money.
