118MM E27 to R7S Adapter Converter LED Halogen Light Bulb Lamp Holder
A part of the review has been auto-translated.
The product idea is fine, the applied technology is also OK. Refer to the inserting procedure of the line form bulb, it i complicate. Both end connectors are hidden, the bulb insert is a challenge. After insert of the bulb, the converter screw to the female case is also risky. Touch the bulb by hand is not recommended, hold the converter by hand over the bulb is impossible ( by human hand ). Let me recommend to add to the package a hard paper or plastic U form cover to allow the insert by loading the screw force to the both ends, instead of the center handling. The cover also should be useful to save the converter during the transportation. My piece has been broken, but I was able to repair by glue.
It's a lamp/bulb holder. It works and it's not expensive. What's not to like?
