Lews review: Lew's xfinity speed spool spinning reel

I was fishing on my kayak and I know the drag was tight and then the drag knob flew off and my spool went in the water after i casted . I got the spool back but know I can't tighted or lossen the drag without the pieace. I also just bought this rod and reel yesterday and I was testing it out and this happens now I can't fish. I had high expectations but not now because this happed.
