GU10 Smart Spot Light Bulb Compatible with Alexa, Google Home, SmartThings, 5W WiFi LED Track Light Bulbs, Color Changing, No Hub Required, 4 Pack

I needed 3, so I was happy to have 4 in case one was defective, like other reviews mentioned. All three I installed worked perfectly, though! Initial wifi setup was a little finicky, but I just kept resetting the lights and eventually got them to set the the slow blink so I could add them one at a time to wifi (I did not want to use bluetooth and the auto connect feature (the fast blink) wasn't working). To get them to enter slow-blink wifi set up, turn off switch, count to 9, repeat 2 more times. Repeat this until they slow blink then install is easy. If you've already successfully set up a bulb, don't reset it. You can take it out of the socket while you reset the other bulbs on the switch. If auto connect mode works, you don't need to do any of that though. Just follow the manual and try this if you get stuck. I've set up a lot of wifi bulbs and smart home items to use with google. These are perfect once they are set up. My internet cuts out intermittently (argh, att) and my other smart bulbs sometimes get messed up by this and don't respond immediately to voice commands. I'm working on a solution to the internet issue, but these bulbs aren't affected like my feit smart bulbs. They always respond if wifi is on, even if the internet has been wonky. They are super bright and make gorgeous colors. Well worth it. They do get very warm, though. A little unexpected for LED bulbs, but may have something to do with the fixture casing I have them in.

Connection kept dropping. Did not work well with my Samsung SmartThings Base station or Alexa.

Siempre me han funcionado de manera excelente, deben tener una buena conexión para dar el servicio esperado pero es lógico, muy recomendados :)

Took about <one minute set up lights through Smart Lifr app. Then added to Google home. Took ~1 minute for setup. Works flawless. The guide that came with it is confusing and can explain high returns for this item. The bulbs are bright, well made and change colors as advertised. Google home app showed several preset colors. The bulbs are respond instantaneously to voice commands. You can use Google Home or Smart Life app to control silently. Tried for one week, so can't comment on longevity. 100% satisfied so far. I am not paid or connected to bulb maker

Worked with Alexa and smart things app for 8 months. Then moved fixture and the bulb would not repair. Try resetting using manufacturers options for resetting pairing mode and would not go into pairing mode.
