Pretty awesome service, bottles came in a little leaky but wasn't too big a deal. Nice fast shipping.

Great price and delivery time on live well timer order. Other order of boat trailer guidepost kept getting cancelled so placed call to boatplicity to find out they do not sell that part. An email to me explaining why order was cancelled would have been nice. Otherwise all good.

The unit looks great and shipment was on point. Thanks!

The only issue was the shipping straps on both shocks were broken on one end only! Made it more difficult to install! But for the price I can't complain much! Thanks

Would purchase again from this company.

Is Good Thankyou
