This is my hopefully sufficiently thorough review of the L7C Foldable Crank by LilyDrip. I purchased it and received it today along with the LilyDrip Family.

To use the crank requires to use the knob [either original size or Big Joe] for it comes with no knob. Its length is slightly less than the large crank sold as an accessory for grinders by Comandante. I believes its slightly smaller length is to prevent touching the surface on which an attached grinder rests. When folded I believe a millimetre or two of clearance is attributable to its length. Unlike the cranks by Comandante the L7C is not angled; its shaft is straight with the exception of the ninety degree bend near the point of attachment to a grinder. I understand this design for when folded it would not be flush against the side of a grinder otherwise. The quality of its build is solid and feels like something Comandante would have and should have made. It came in a soft exterior felt or felt-like drawstraing bag with a rough interior excessively large but can be repurposed thus its size is not a disbenefit.

When the crank faces the right side the button faces away from the user. The button is literally a inelegantly upwardly bent piece of metal that when activated pushes what seems to be a spring-loaded metal plate in the middle of the square shaped mechanism towards the user. To use the crank the button must be depressed only until the crank is moved towards the user then the crank must be pulled continually towards the user until the aforementioned metal plate returns to its original position thereby locking the crank into its upright position. To reverse the action the button is depressed and gravity can finish but I suggest to hold the knob to make it fold gracefully. It truly is quite nice when folded and the primary reason to purchase the accessory. However, one extreme error in design makes this an accessory I almost wish not use. Their grave oversight is the lack of a cover. The product description says to be used with the plastic cover but the plastic covers are attached to both cranks by Comandante. This means an attached grinder has got no lid and beans will fly out if not held down on a level surface or the crank is rotated slowly regardless how level it is held in hand. This is a very bad choice of design and a huge glaring ugly flaw. They should have incorporated an inbuilt cover of the same material as the crank and square central mechanism. Besides this apodeictic disappointment it is no less ergonomic or difficult to use than either crank by Comandante. I like to use it and even more like to fold it when finished to save space near my coffee station although not having a foldable crank was not much of an inconvenience when on display. Coupled with the very elegant tough leather bag by Comandante in production no longer this is a very stark improvement for efficiency of space within the bag comparative to removal of either of the cranks by Comandante. I have got one and mention it based on experience. The slot on the left for a crank can be used for something else.

With regards to price I cannot possibly know if its current price of US$59.99 is marked up egregiously for I am not their accountant and thus know not how much money it costed them to build one or any of the other backend factors. Surely it is marked up but I hope not by much. My conjecture is this and the L7X cranks garner no profit margins in the realm of Apple Computer or probably even Comandante. It was not an obvious website to find and I suspect many persons whom possess grinders by Comandante know of its existence. I hope this review makes it more prominent for it truly is worthwhile even if used only when travelling. The takeaway is that it is very nice and convenient to have and use but not absolutely necessary.
