No sign of a shutter either.
The spooky thing is, when I saw this post earlier today, I was in a meeting discussing laser safety and conformity with EU Directives!

And a sleeved earth pin.
And a UK plug can be inserted upside down as there is not enough plastic round the outside.
No, all sizes including some with much less laser power.
If you are going to so boringly pedantic then please be boringly accurate when you post corrections to other peoples posts.
The supply voltage in the USA ( United States of America ) is a nominal 120 Volts RMS AC In practise it can be somewhere between 110 to 120 Volts RMS AC and 117 Volts RMS AC is often used as a design parameter.
The published tolerances ( nominal + % and - % ) on the nominal supply voltage vary between the many supply and generating companies that are active in the USA and these can be as great as plus or minus 20% though these extremes are mainly in rural areas.

I have a number of the adaptors shown and I do use them to elevate battery chargers over the other plugs in my extension lead. Also to allow use of battery chargers with USA style plugs although still rated 230 volt. Used with knowledge they can be handy, but only use in extension leads as there are no fuses so used in an extension lead there is still a fuse in the plug. Used with French of German Plugs there is no earth so that is out.
The 110 ~ 127 volt systems one needs care with as USA is not the only country to use it. Algeria also uses it much closer than USA. And in the USA the systems change it is not one single system.
Ebay can be a cheap way to get what you require, but it is let the buyer beware and safety is down to the user.

Back to the dangers of laser beams. This article was mentioned in another forum relating to aviation safety
quoting from http://www.laserpointersafety.com/page52/laser-hazard_diagram/laser-hazard_diagram.html
A 5 milliwatt laser: a distraction 2 miles away
In the United States, lasers sold for pointing uses cannot exceed 5 mW. The diagram below shows the hazard distances for a 5 milliwatt “U.S. legal” green laser pointer with a 1 milliradian beam divergence:

A 5 milliwatt laser: a distraction 2 miles away
In the United States, lasers sold for pointing uses cannot exceed 5 mW. The diagram below shows the hazard distances for a 5 milliwatt “U.S. legal” green laser pointer with a 1 milliradian beam divergence:
- It is a potential eye hazard from the pointer to about 52 feet.
- It is a temporary flashblindness hazard from the pointer, out to about 260 feet. On the diagram, this is illustrated in the inset photo “Near-flashblindness” which shows what a 5 mW laser looks like at 350 feet.
- It is causes glare and is a disruption hazard from about 260 feet to about 1,200 feet. This is shown in the “Glare” inset photo where the runway is not visible.
- It is a distraction hazard from the pointer to over two miles (11,700 feet). The distraction can be dangerous during a critical phase of flight, such as takeoffs and landings.
Why would you use an adaptor like that to plug a UK plug in?

With all the dodgy gear pumped out by China, I would suspect the whole kit.
The leads are renowned for having undersized conductors. Some Class I (EDIT) kit is not even earthed.
I would change your lead for a UK-sourced one and buy a multimeter with which you can test continuity on your machine between the earth pin of the power inlet and the casing/ screws.
If you don't get continuity, RUN!!!
