Dr. Zak, you and Dr. Lunin manufacture and sell fly-fins.
But more importantly:
We: Dr. Zak and Dr. Lunin have invented Fly-Fin and made it work.
As you may have already researched there have been repeated attempts for 40 years to make a usable Fly-Fin. FRPGear has finally got it right. Only RazeR69 is complaining, but still using our Fly-Fin invention. Our Fly-Fin is probably so good - even when someone picks a wrong size like Raze69 did you can still make it work without being an educated Ph.D.
Here are more facts:
RazeR69 payed with Paypal:
Hydrofoil fin S-Glass Fin, Tuttle Box. 1/4-20 $290.00 USD + Shipping $24.50 USD
FRPGEAR paid: PayPal Fee-$14.14 USD
FRPGear ended up with 290-14.14=$275.6US. Subtract taxes, materials and labor cost. It means Dr. Lunin and I do not do this for money.
We ship it with declared value of $200 for shipping cost reduction or with no declared value when customers with high import tax ask. So it should not be high custom cost on import.
Yes, you will need to pay your own shipping cost of $24.50 if you want to ship it back for a complete refund. From your recent post I see that paying for the return shipping was an important issue for you. From your other posts I see that you have decided to keep this low cost model in order to get 50% discount for a significantly more expensive model that would be a correct fly-fin for your board. In other words, instead of buying $900 fly-fin you purchased $290 fly-fin in order to become eligible for 50% discount on $900 fly-fin. In result, you would pay as low as $290+$450= $740 total for two: $290 + $900 fly-fins instead of paying $900 for only one fly-fin. Dr. Lunin has already discussed these options with you after you have been trying to cancel you $290 order with PayPal when you found the same but lower price Fly-Fin available on eBay for $288. eBay does not provide benefits on the second purchase.
We do not compare Fly-Fin cost to a regular fin cost. We compare Fly-Fin cost for light wind planing to the cost of other options for light wind planing. For example, I have purchased a used 100L AHD and new NP racing sail 5m for $450 total. With frpgear 2018-Winglets I (80kg) get on planing at 9 knotes compare to 13 knots wind with a regular fin. How much money do you think I need to get on planing at 9 knots wind without fly-fin?
When you refer to your own fly-fin I am getting confused because you are showing pictures of frpgear fly-fin. Yes, you added more fin area and adjusted setting angles. But it remains frpgear fly-fin. As they like to say today: "If it looks like, works like, used like, made like, promoted as, purchased from, made out of frpgear fly-fin it is frpgear fly-fin."
Nicht war?
