I'm giving a 5-star review for the product itself! The paper quality is incredible, and the layout of the undated planner is perfect. There is no fluff inside-- many planners have tons of extra crap in the margins or design that waste page space, not this one!
The size of the planner is ideal-- small and ergonomic while still being sturdy and tons of pages. I love that the inserts can be switched out after one booklet is full.
My only complaint, which may not even be fair, is the shipping cost. I am in the US, and the cost of shipping was equal to the cost of the planner. This was the only thing that discouraged me from purchasing before I was sure I'd like the product. I would have preferred to pay a higher price for the planner itself to offset the shipping cost-- to make it worth my while I ended up purchasing 2 planners.
Luckily this gamble paid off for me, because I adore this product despite years of allegiance to the dateless planner made by Open Sea Design Co. I will be singing the praises of this product to friends and family but with the caveat that the shipping cost doubles the price of the product.
