Great option for quick and efficient replacement and upgrade of sensors.

Bought to replace 15 year old sensors that were malfunctioning on my Liftmaster Jackshaft garage door opener. They were easy to install, align and worked immediately after plugging in the unit without any programming or cycling. 4 Stars because the wire connectors are not the best as they require a bend in the wire, as they run perpendicular to the actual wires which looks bulky and unsightly.

Works but Also Harmful
3 months ago
My garage door opener needed new sensors and this seemed a good fit. Easy to install and it works. That’s also where the pros end.
It’s priced higher than HD so not good value even when I paid using CT money.
It has a Prop 65 warning because it contains lead and other toxic chemicals that are known to cause cancer and harm productive health. No other details can be found on the instructions or Chamberlain website. First of all, it is absolutely UNACCEPTABLE to continue to use known toxic substances to poison the people and the planet. In this case, Chamberlain must explain WHY it continues the toxic practices. Secondly, affixing a warning label is the bare minimum to be compliant with Prop 65 and far from enough; Chamberlain must specify the specific types of toxins used, how they were used and concentration. Thirdly, it must include any harm mitigation strategies. I turn off power to the garage door opener so the sensors are off most of the time; not sure if it helps with harm reduction but they should last longer this way.
I strongly recommend against getting this product if you have young kids or plan to have one.
It is also disappointing that CT still carries this toxic product instead of sourcing safer alternatives that don’t use lead or other toxic materials.
No, I do not recommend this product.
