What to know before buying
Listing details to confirm
Listing details conflict on dimensions: the size field gives 100"L x 92"W, while the feature text says 100"W x 90"L. The blanket is titled King, but the model name calls it a throw. Confirm dimensions and selected size before buying. Customer feedback also criticizes cord length and reports that the blanket can slide off the bed. The manufacturer cautions not to cover the controller while in use. The listing says larger sizes have two controllers, and customer feedback is mixed about the controls and heat output. The 6ft power-cord and 11ft controller-cord lengths are listing claims, while customers describe the cord as too short.

Customer feedback is mixed on quality, heat output and reliability. Customers also differ on the controls and whether the blanket is worth its cost. The lightweight feel is appreciated, but cord reach and staying in place draw criticism. These concerns matter for a King blanket intended for bed use, especially if outlet placement or a secure fit is important. The listing claims two controllers for larger sizes, but that feature does not resolve the reported differences in control satisfaction.
Positive themes
- Some customers appreciate the blanket's lightweight feel.
Negative themes
- Customers criticize the cord length and report that the blanket may slide off the bed.
Mixed feedback
- Feedback is mixed on product quality, heat output, reliability, controls and value.
