No it isn't, save your money and buy a laser of good quality, you won't regret it. I would recommend always spending a minimum of $140 unless your looking for a cheap low power pointer. Of the 5 lasers that I built myself the cheapest one was $140 just for the parts, but I know exactly what's in them and that they are high quality lasers. The one cheap 532nm green that I ever bought broke after only 10 days.The cheapest one is $140, thats a bit much.
I have purchased all of my batteries and my 3 chargers here:Does this:
Come with any battery or anything? If not, where do I buy a battery and a charger?
Yes they will work, but I recommend you stay away from those generic blue ones with no brand name, I have some and they aren't very good. Also Ultrafire are considered low quality. The Trustfire will be fine in that laser.
