These under-cabinet lights really helped light up the counters all the way around my kitchen. My kitchen was previously lit just by a fluorescent fixture on the ceiling and was relatively dark, especially on the counters. I installed 4 of these 3-packs and the whole room feels much brighter now. The counters are now very well-lit. I would really probably rate these more like 4.5 stars, but that's not an option and I don't think the minor issues I had with them were worth knocking a whole star off.The customizability of these lights worked very well for my use case. My kitchen has cabinets in 4 different disjoint sections (one on an island, one on one side of the sink, one between sink and stove, then one on the other side of the stove.) Installing a hard-wired solution would have been a huge pain (and also quite expensive,) requiring running new power lines through the walls in several places. Being able to just plug these into the AC outlets along the wall under the cabinets saved tons of effort and likely at least hundreds in installation costs. Plus, if/when I or a new home owner wants to replace these, it's far easier to do this way than with a hard-wired solution.Being able to install these without the switch in-line and instead plug them into smart plugs worked out great. I had already installed a Kasa smart switch on the main light in my kitchen anyway, so I just got 4 Kasa smart plugs and set them to turn on and off with the main light, then plugged these four sets into them. This way, there's no need to run wires through the walls or behind the stove or anything like that. Each set is just plugged individually into an outlet with a smart plug and the whole room lights up when I turn on the main light.The customizability of this set is hard to beat. Each strip can be connected either with a short barrel adapter or with a cable. The cable worked great for turning corners or when the strips just needed to be a little farther apart and the barrels generally worked well for when the strips needed to be placed end-to-end. The only problem I had with this was one of the barrels apparently just wasn't making a good connection and was causing the strip downstream of it to occasionally flicker or run dim. Since I had unused barrel connectors, though, I just swapped that one out with another one and it's been working great since then. Being able to simply leave the switch out of the circuit is a great for my use case, since I want the lights to come on at full brightness whenever the smart switch turns on anyway.Installation was relatively straightforward. Just make sure to peel the plastic cover off of the metal strips, attached the adhesive strips to them, then place the adhesive strips underneath the counter where you want the supports to attach. Once the metal plates are installed in position underneath the cabinet, then you just snap the supports onto the light strips and then they hold magnetically to the metal plates. I've had these up for several months now and no issues at all with the lights detaching from the metal plates or the adhesive that holds the plates to the cabinets letting go. Do make sure to remove the plastic backings, though, as they won't hold up with those on.I have had a few relatively minor issues with these as mentioned at the beginning, though:- One of the barrel connectors was apparently defective. No problems after replacing it with a spare one, though.- The adhesive on the clips designed to hold the wires up against the under side of the cabinet is rather poor. These all fell off very quickly. I replaced them all with Command strip hooks and that solved that problem. This only applies to the clips designed to hold the wires up, though. The adhesive that holds up the lights themselves works great.- There's about a 1-second delay between when the lights get power and when they actually light up. This is really just a slight annoyance, but it does create a noticeable delay between when the smart plugs turn on and when the lights actually light up. I know the delay is in the lights and not the smart plugs, as I can hear when the relays in the smart plugs switch. This is not a huge deal, but it's a minor annoyance that's worth noting. Of course, the lights do turn off immediately when power is turned off.- The AC/DC transformers on these are quite large. The transformer is built into the plug, so the only way to mount the transformers up underneath the cabinet out of sight is to use extension cords. This is especially true when you also have a smart plug between the transformer and the wall outlet. It was really a lot of bulk sticking out of the wall and looked kind of unsightly until I got some short 90-degree plug extension cords that allowed me to mount the transformers and smart plugs up underneath the cabinets where they are out-of-sight.- The light strips do get pretty warm. Of course, I'd expect that with incandescent bulbs, but it seems surprisingly warm for LEDs. This hasn't been a problem at all for me, but you'd want to make sure that these are placed where kids or pets wouldn't touch them and get burned.Overall, despite a few minor annoyances, these paired with the smart plugs have worked great for my use case for getting under-cabinet lighting that's easy to control without expensive tearing up of walls and installation of new AC power lines by an electrician. My kitchen is much brighter than it was before, which makes the kitchen feel nicer overall, but also makes food preparation easier by lighting up the counters well.

This is a great light I have under my kitchen counter.The brightness is adjustable and it really helps lighting up the areas under the counters.Installation is real easy and flexible with tape, screw brackets or magnets.

I have had this light bar configuration for over a year with plenty of use. I haven't used it with a smart outlet like it says you can but I have used it with manual control and it has been fantastic.I converted my guest room reach-in closet into an office space and put these up on the inner wall that face in towards the closet's back wall so it lights up what would have been clothes and storage.I decided to repurpose these for my bedroom since I am installing recessed lighting in the closet ceiling. I used the adhesive and wish I didn't. The adhesive is way too strong for wall paint (at least for my matte finish). It's good that the adhesive will hold long-term but I wish they used the 3M style "easy remove" double-sided adhesive tabs that do a great job of holding things to the wall/ceiling/overhang without tearing up the paint/drywall. Removing these was a serious chore and I definitely damaged the wall but luckily it's not something anyone would ever see due to where I mounted them and the adhesive strips are small so the damage size is minimal.That said, if you're putting this on the back of a TV or underneath a cabinet etc it's going to hold for years without fail and probably not cause any meaningful damage. So, I'd reconsider using the provided adhesive and instead get some 3M Command Strips which are more than strong enough to hold something like this while still being easy to remove if/when that time comes. Or just use magnets instead!I am not going to ding a star since the product I bought and am reviewing is the lighting system not some double sided tape.It's a fantastic product overall, does what it's supposed to do. I never used a remote or anything I only ever controlled it by the provided inline controls.I highly recommend it and being that it's 12v I can see it being expandable to double maybe even triple its length/amount of lights.
