have their effect

I actually read the reviews and I chose to order this item despite the negative comments. Realistically they are not expensive, and there for the price.
So yes lamps are fragile but not more than more expensive. we must follow the recommendations and not act as an ox! so be careful so slightly unscrew the transparent section to access the switch (that some users may have not seen!) set to ON, recover from careful way the transparent part. and then to implement them not to press like crazy on the hat, but make a pre hole and then position the lamp in the pre hole, it avoids breaking the mouthpiece which must be in the ground, which is plastic.
They focntionnet all and make their effect. I will also probably be ordered else. I think after this type of article is not perennial and can be expected to change in queqleus years.
