Took a minute to find but then everything went well

Great prices will have to update once I receive the wheels

Really straight forward

This was the first time I had ordered from Boatplicity, not having come across them in my previous searches for gear. As what I was looking for was a brand name product I selected purely based on price. The purchase process went seamlessly and the two items I bought showed up within a day of each other, both well within the delivery date promised. The items were well packaged and arrived undamaged, and were exactly as I had ordered and expected.

Wow, the price was unbeatable and the delivery was quick. The props came in perfect condition, couldn't be happier.

Easy process
