this is the one I use and at over a year in use I don’t smell any leakage and my misses is paranoid she would let me know in a heartbeat they are easily double the price of the normal ones you see listed here and for good reason they have reliable results and last far longer work with way more fans,.
@Paranorman what was the cheapy you got? I’ve got to deal with odor to keep my hubby happy 
I personally love the fragrance 
But am on a budget and only plan on flowering 2 plants at a time
Thanks in advance my friend!
