Mr. Li still felt uneasy as he looked at the elevator being installed in the villa. Three months ago, he accompanied his parents to see a house. The elevator in the model room was quiet, smooth, and luxuriously decorated. The elderly praised it as "much easier than climbing stairs". However, after signing the contract, I went to the construction site to check and saw the same brand elevator stuck on the floor. The repairman had just climbed onto the car when a rusted steel beam "clanged" and fell. Originally, the model room was an imported machine, but what they bought was a domestically produced "downgraded version"

Hidden security risks

The elevator quality inspection report shows that 23% of household elevators do not have standard safety clamps, and 15% of speed limiters have slow response. A certain brand even replaced 304 stainless steel with 201 stainless steel, saving 40% of costs, but reducing corrosion resistance by 70%, and rusting in just three years. The seemingly dignified elevator actually carries hidden risks.

Maintain trap and design imbalance

Lifetime maintenance "often becomes a trap of" repair not replace ". Ms. Wang's elevator motherboard in Hangzhou was damaged, and the manufacturer refused to replace it on the grounds of over warranty. The third-party quotation reached 28000 yuan, and the contract even stated that "the core components are only guaranteed for 2 years". Some high-end residential areas have shallow elevator cars, and furniture is often stuck; Some villas have removed ventilation openings in pursuit of panoramic glass, making the summer heat unbearable.

Energy consumption trap and 'pseudo intelligence'

Low cost elevators often use inefficient motors, which consume 70% more electricity per day and cost nearly 20000 yuan more in ten years. The so-called AI voice and face recognition functions have low recognition rates, ineffective dialects, and are almost unusable for the elderly and children, ultimately relying on card swiping.

Rational choice, safety first

The key to avoiding pitfalls lies in system judgment: checking authentication, nuclear components, examining energy efficiency, inquiring about maintenance, and testing intelligence. Mr. Li ultimately chose the model that was 20% more expensive, as the safety gear and speed limiter were more reliable and enjoyed full cycle maintenance. Three months later, he sighed and said, "Watching my parents ride the elevator with peace of mind and my child press the button with a smile, I realized that safety is more important than affordability
