3. Jacuzzi Hot Tubs

Jacuzzi is a household name in the hot tub world and often praised for its energy-efficient performance. However, despite the brand recognition, it averages just 3.5 stars in consumer reviews—largely due to poor after-sales service.

Common complaints from customers include:

• Warranty delays or refusal to replace faulty parts
• Heaters that stop working correctly not long after purchase
• Inferior materials causing recurring malfunctions
• Limited flexibility in configuring energy-efficient features
