Better than expected
Color: 200LED
There are great. Better than expected. We trashed our recently new lights and needed something fast as a replacement. Bought these on a whim. Was not fond of the smaller LED's but had no choice at the time. And these are probably the best lights I've had for the tree. So many settings and colors. Bright and efficient. Not sure how long they'll last but probably a good while.

Good Quality
Color: 200LED
These are outside on a balcony rail. They get rained on regularly. Ninety percent of the time the are warm yellow steady on. I can't comment on the other features. Remote works fine when I switch from warm yellow to multi color. Must point remote directly at the receiver.

Lights are perfect for my tree!
Color: 800LED
Love these lights! I purchased the 800 LED lights for my 7.5 foot tree. I was able to wrap each branch to give it the “pre-lit” look with quite a bit left over to fill in any space that needed more light. I normally don’t use colored lights so I love the option to do warm white only, but it can filter through the other color options- multi or mixed colors. Remote works just fine, it has a sensor on the plug part that you have to point directly at to work which isn’t an issue for me since I plugged mine into the outlet right next to the tree and I can get to it easily. With the 800 lights, there’s not a connector on the end to attach another strand, there’s a connector on the smaller strands of lights to connect multiple together. Overall super happy with this purchase and just purchased the 200 LED for my son’s bedroom tree 💙

Multi colored changing lights
Color: 200LED
These lights are well worth the expense. You get so much from a small price. A remote control that turns the lights on and off. They can change the settings in a single touch The lights sequel through solid colors, multiple colors, flashing, blinking,, soft, vibrant to name a few. . The lights are beautiful and bright.. Great buy. I hope they last for many Christmases.

Bright, Fun, and Easy to Customize
Color: 200LED
These Joomer Christmas lights are a great way to add some extra color and atmosphere to your holiday decorating. I really like having the option to switch between warm white, multicolor, or a combination of both, with several lighting modes to create different effects. The remote control makes everything very convenient—you can change the colors, brightness, speed, and even set a timer without having to get up. The four brightness levels are especially useful when you want softer lighting. Another big plus is the ability to connect up to three strands, giving you up to 195 feet of coverage. They’re also waterproof, making them suitable for both indoor and outdoor decorating. The memory function is a nice touch because the lights remember your previous settings. Overall, these lights are versatile, easy to use, and offer plenty of options for creating a festive look. They’re a fun addition to a Christmas tree, porch, yard, or party decorations.

Great Buy!
Color: 200LED
I've always wanted color changing lights for my tree, and I'm glad I took a chance on these! There's so many options for led strings, but these were on sale for about $16 and reviewed well. One string fit my 6.5/7 foot tree perfectly, and seem to be pretty well made (none of the cord separating like you get with traditional light strings nowadays). So excited to not have to connect multiple strings to do my tree anymore! Lights are bright, and the mix color option (you get multi and white at the same time) is my favorite. Remote is handy, and I was pleasantly surprised to find that there's a manual remote built into the cord so you can change settings if you lose the remote or the battery dies. Huge bonus for me since I hate buying the little watch batteries the remote takes. Video is the lights set to slow-glow and mix color. The twinkle and flash settings are similar and way too intense for my tastes, but there's a good number of options, and being able to switch between multi and white is great. Fantastic buy for what you get!

Great lights but flawed remote
Color: 200LED
Ordered these lights last year for our tree and loved them. All the options for color and timer were great. Went to put them up this year and found the remote was broken - somehow the little slot that holds the battery has slid up into the remote so that it can't be removed? I even tried to use my thumbnail to pull it out and the plastic snapped. It's never coming out now. So now all the options that we loved are no longer available. Can't set the timer or change the lighting or pattern. Very disappointed that we only could use it for one season.
