Let me preface this by saying my tech level is extremely advanced, so any tech issues I have with a product are usually product-related and not user error. Setup with these was ok, but they do not detect well and will take multiple tries with Alexa to finally find and install all of them if doing more than 1 or 2 at a time, but I was willing to accept that. I have been working with tech for 30+ years now, so I'm used to back when tech was far more difficult to setup and configure. I started with 12 Sengled Bluetooth bulbs and they worked great. So great that I got another 10, and then the problems began. Tying to install the next 10 took many many tries, then during discovery on one of these multiple attempts, it reset ALL of the Sengled bulbs in the house. So now I had to re-name and re-group my original 12 Sengled bulbs while continuing to fight with the new ones. After way more effort than they are worth, I finally got all 22 Sengled bulbs setup and working. And then the next day, one of them was completely lost to the Alexa app. Just deleted. So no more controlling it. At this point, there is no way I would go through the nightmarish discovery again, and will no longer be using Sengled Bluetooth bulbs. It is worth mentioning that I have 32 Hue bulbs in the house and all are absolutely flawless. Perhaps I should have just gone with the Wifi version of these Sengleds, as I have a solid Asus Tri-band WiFi 6 mesh system that still has plenty of room for more devices, but the Bluetooth were cheaper and I planned on using them in areas where things like scenes, hue wall switches, and the richer Hue colors were not necessary. But after the negative experience I have had with them in terms of maintaining a reliable connection, I will be looking elsewhere for a cheap candelabra Hue alternative simply for budgetary reasons with a total need of 25 candelabra base lights for 2 chandeliers. Also worth noting is that I have 9 echo devices throughout the house, evenly distributed, as is my WiFi mesh system. So it is not an issue with these bulbs being too far to maintain a reliable connection. It is just poor programming within this product for more than a dozen bulbs. So, who SHOULD use these? 1. People who plan on using fewer than 12 MAY have an ok experience, as mine seemed fine until I exceeded that number, and I have seen other reviewers who experienced the same. The color on these is surprisingly good for non-Hue bulbs. 2. People who don't mind the fact that when using Alexa to control them, you can only say specific colors that Alexa recognizes by name via the Alexa App. In other words, no full 16 million color gradient. If you want the full gradient, you can connect them via the Sengled Bluetooth App (Not the Sengled Home App), but you will lose all Alexa/Voice functionality - you can have only one or the other, not both. 3. People who have an outdated WiFi setup, as any pre-WiFi-6 setup is going to give you issues once you exceed 2 dozen or so devices on the network, so its better to throw some Bluetooth bulbs in the mix and reserve your Wifi for devices that truly need it. However, upgrading to a Wifi-6 system would be a better option across the board for anyone looking for better network functionality, especially when there are multiple users on at once, as it tends to be significantly better at distributing bandwidth to give all devices a better experience. Who should NOT use these? Pretty much anyone else, especially if you want more complete control over the bulbs, including 16 million colors, color scenes, or rainbow effects where the bulbs change colors automatically. If you have a WiFi-6 setup, you should just get WiFi bulbs. I don't know how the Sengled WiFi bulbs are, as my experience with these has been poor enough that I will be avoiding Sengled bulbs entirely, but Wifi certainly gives you a lot more brand options in the now flooded color LED smart bulb market. Just avoid any bulbs that can only be controlled with a crappy little remote with no smart functionality at all. You deserve better than that. :) If you have the money, go with Philips Hue. Philips are leaders in lighting beyond just smart bulbs. Their lighting products always tend to be superior to the competition in terms of quality of construction, the quality of the light they emit, the features they offer, and their longevity. I have been using Philips bulbs in my projectors for years, along with the 32 Hue bulbs plus light strips throughout the house, and there really is no comparison to any of the knock-off brands out there. They are well worth the extra cost if you can swing it. But for 25 candelabra base bulbs in 2 chandeliers that do not require scenes or any other advanced features (like syncing the color and flashing of the lights to music/movies via PC), I cannot justify the Hue cost (at $55/bulb!), so my hunt continues, as these Sengled Bluetooth bulbs have failed miserably for me.
