Query: Money!

i got this item for my 13th b-day and it was not what i expexted, this item is good if you are rich, i put some rocks in and turned it on, you had to let ti go for like a month almost but i never got to finish it becase it needed to be pluged in and it was running up the electricity bill and was costing us more money than it was worth so my mom made me unplug it. even though the rocks came out smother then they were when i put then in even though they were not in for the whole time they were also not the right shape to put it on a necles or the rings that they give you and when you do finaly get then on they fall of in like 2 days cuz the glue was not strong enough~ botton line i think you should not waste your time or money on this item~
