Quick answer

Choose the Menstruation Crustacean Crab if you want a lavender-scented, gift-ready microwaveable heating pad for cramps. Choose the Octopus if you prefer an unscented option and want to spend less upfront.

Scent is the clearest dividing line

The Crab is the only one of the two with a supplied lavender scent. That makes it a better fit if you find scent soothing during cramps, but a worse fit if you are sensitive to fragrance or share a bed with someone who is. The Octopus has no scent listed in its catalog facts, so treat it as the safer neutral choice when fragrance is a concern.

Price and gift appeal trade off

The Octopus is listed at USD 15.49 against a USD 24.99 comparison price, while the Crab is USD 16.99 against the same comparison price. The gap is small, so let scent and gifting decide rather than the dollar difference. The Crab is explicitly positioned as a gift for a girlfriend, sister, or bestie; the Octopus is framed more as a personal cramp-relief pad.

Both rely on the same microwave routine

Neither product comes with a rechargeable battery or adjustable heat setting in the supplied facts. Both are microwaveable pads: the Octopus instructions specify one minute in the microwave before applying to the affected area. That means your choice is about shape, scent, and price, not about heat technology. If you need consistent, timed heat for long sessions, a microwaveable pad may not be the right category for you.

Key trade-offs to weigh

  • Scent vs neutrality: The Crab includes lavender scent, which can feel calming but may bother fragrance-sensitive users. The Octopus has no listed scent, so it stays neutral. If you are unsure about fragrance sensitivity, start with the unscented Octopus.
  • Gift vs self-purchase: The Crab is explicitly marketed as a gift for a girlfriend, sister, or bestie. The Octopus reads more like a personal cramp-relief tool. For a gift, the Crab's presentation and scent do more of the work.
  • Upfront price: The Octopus is USD 15.49 and the Crab is USD 16.99, both against a USD 24.99 comparison price. The difference is small enough that it should not override scent preference.
  • Heat method: Both are microwaveable pads with no supplied adjustable heat or battery option. The Octopus specifies a one-minute microwave time; the Crab's microwave time is not listed. Follow the individual product's heating instructions rather than assuming identical timing.
