**** The reception of this product has been mixed, with customers reporting varied experiences based on their specific uses. A common theme throughout the feedback is a significant concern about the durability and safety of the casters. For some users, such as those replacing wheels on a Coleman cooler or a portable chop saw stand, the casters performed as expected, improving mobility and ease of use. However, others had severe issues, particularly those using them on wheelchairs. One reviewer highlighted a dangerous experience when the flat profile of the casters caused the wheelchair to tip over during navigation of small thresholds, emphasizing that these casters are unsuitable for ultralight wheelchairs. This reviewer insisted they should not be sold for this application due to the serious risk of injury. Concerns about durability are prominent, with multiple customers reporting that the casters broke within weeks or months of light use. Some have opted to revert to original casters or look for alternative brands to ensure safety and reliability. Overall, those using the product for more casual applications appear satisfied, while customers needing reliable performance on wheelchairs express significant disappointment and warn against their use in that context. **
