1. Light Therapy Ineffectiveness
Product Defect · Major · 2.2% of buyers
The light therapy feature does not provide an adequate wavelength, resulting in users feeling no benefit from the treatment.
"Not an adequate wavelength"
"Not an adequate wavelength or robust vibration or deep enough heat to make me feel I'm getting any benefit"
2. Vibration Weakness
Product Defect · Major · 2.0% of buyers

3. Heating Function Ineffectiveness
Product Defect · Major · 2.0% of buyers
The heating feature does not get warm enough to provide any noticeable benefit during use.
"deep enough heat to make me feel I'm getting any benefit"
"Not an adequate wavelength or robust vibration or deep enough heat to make me feel I'm getting any benefit"
4. Vibration Activation Confusion
Usability Issue · Minor
Vibration only activates when fingers are placed on specific bars, causing confusion and inconsistent operation.
"You actually want to put your fingers on these bars and that will activate the vibration. If you don't have your fingers on those bars, then it won't vibrate."
5. Missing Double Needle Capability
Missing Feature · Minor
Cannot use a double needle due to side-loading bobbin design, limiting sewing versatility.
"It is a side-loading bobbin, which means the needle faces to the side, which means you cannot use a double needle with this machine"
"If you intend to make a t-shirt and you don't intend to also buy a coverstitch machine, this will be an issue"
6. Missing Color Selection
Missing Feature · Minor
Customers cannot choose their preferred color and receive a random one, leading to dissatisfaction.
"you can't pick a color and they just send you one"
"I prefer bright colors but haven't seen them in a physical store to choose from"
