It is now six months I use this little laser. I find it very convenient (it takes up very little space) and the value for money is very reasonable. It is very useful in small parties (15 to 30 people for my taste), it will not help in an evening wedding (I've experienced, and it was totally useless). The only downside about this product: I think the red is not very strong compared to green, and the laser is plastic so ... very fragile!
I recommend it all the same for small parties, it will prove its usefulness far!
