Quality adapter and at a very good price. If you have screw-in bulbs and a bayonet socket in the fixture, no problem!!! You get this adapter and do your job!!! Truly reliable, I highly recommend it.

It does exactly what one wants it to do. To switch from the old Bagione to a classic screw-on.

It works perfectly! Conversion from B22 to E27. Be careful if you have a borderline lamp holder, as it adds "length" to the bulb.

Unfortunately, I couldn't see if it works because when I tried to connect my bulb, it broke from the inside

It does exactly what it's supposed to do.
I put it in old fixtures so now I don't need to have a socket and two types of bulbs.
I also put a wifi bulb in one and it works great!
