I really like it. It's very well balanced & feels nice in the hand, it is very solid construction & very easy to clean. I went with the classic style "clapton" tips instead of the see thru quartz, as I like the better heating efficiency. Which brings me to my only downside with the King, which is the battery size. A nectar collector is meant to run for 30-45 seconds, & 950mah; which is an upgrade from the Seahorse Pro Plus at only 650mah... has you at 60% battery after just a few cycles. It's fine for home, as I wouldn't really bring this piece out with me anyways.
I'd say a heavy user like myself would have to charge it 2x a day, & that's not using it exclusively.
I HIGHLY recommend getting the bubbler attachment: don't bother filling it with water... you'll drink it, & where you gonna put it where it won't fall over, lol? BUT: the attachment adds length to the chamber, allowing for a much cooler & smoother/larger hit... even without water.
I give the Seahorse King 4 stars, I give INHALCO 5 stars for fast shipping & great customer service & price point.
