Looks good, and gets the job done.
It is kind of difficult to clean, but other than that none.
I got this awhile back, (about 4 months or so) and its worked great. It drops my tank into a very comfortable position and helps me stay tighter to my bunker. I think the lightning drop looks better than the flame my brother has, but thats a personal opinion. However with all the bends in the design this is somewhat hard to clean, and takes a good 5-10 minutes to clean it completely
This is a good product for the price, and I definetely reccomend this drop, but have to give it a nine due to hard clean-up
