You not only want to pick the right product for your specific needs, but also choose one that's reliable and respected among other buyers. Before you purchase your next gadget, you may want to see what the folks at the American Customer Satisfaction Index (ACSI) have to say. The top brands for customer satisfaction In a new report released Tuesday, ACSI picked the top brands for customer satisfaction. Based on a consumer poll, the American Customer Satisfaction Index (ACSI) Household Appliance and Electronics Study 2025 looked at consumer opinions about TV, PC, and household appliance brands. So, which companies came out on top? TVs Among television buyers, Samsung led the way with an ACSI score of 83 out of 100. ACSI said that Samsung continues to be a pioneer at cutting-edge technology and setting the standard in the higher-end and higher-priced TV category. Tied for second place were Hisense and Vizio, each with a score of 82. These two companies are grabbing more customers in the US by forming relationships with retailers and offering high value for the money. Tied for third were LG and TCL, with scores of 81. Bringing up the rear among the top vendors was Sony with an ACSI score of 80. Also: The best TVs to buy in 2025 The individual scores remained largely consistent from year to year, ACSI explained. The highest marks cover specific attributes for TVs, including image quality, durability, ease of setup, and ease of using the remote. The lower marks factor in the outcome of service repairs, the courtesy and helpfulness of technicians, repair timeliness, and call center satisfaction. PCs In the PC market, HP was the leader with a score of 83, stealing the top spot from Apple, which garnered a score of 82. Here, HP outshined its rivals in overall satisfaction due to its quality products and strong value for the money, ACSI said. Also at 82, Dell showed a 3% improvement from last year, helping it tie with Apple for second place. Samsung and Lenovo were hit by modest declines, earning scores of 81 and 79, respectively. Also showing small declines, Amazon with its tablet lineup grabbed a score of 78, while Asus came in at 76. Rounding out the pack were Microsoft with a score of 76, and last-place Acer at 75. Also: The best laptops of 2025 Among specific types of devices, desktop PCs earned a satisfaction score of 84, a gain of 2% from last year. The score for laptops stayed the same at 81. Lower down the list, tablets merited a score of only 77, a drop of 5% from last year. "The effort to harness new technology, cater to growing customer demands, and compete with other global leaders has led to high ratings across nearly all the individual characteristics measured in the survey," ACSI said. "Computer design leads the way, followed closely behind by the availability of software or applications and graphics/sound quality. Meanwhile, call center satisfaction is the lowest-rated aspect of the PC user experience." Vacuums For the first time, the survey also measured satisfaction with vacuum cleaners. Here, Samsung was again in the lead with an ACSI score of 82, followed by Shark at 81, Bissell at 80, and Dyson also at 80. iRobot's Roomba robotic vacuum cleaner scored 78, ahead of Dirt Devil and Eureka at 77 apiece. Electrolux and Hoover tied for last place with ACSI scores of 76. Also: The top 10 robot vacuums ZDNET readers are buying in 2025 For this category, ease of operation was the top benchmark. The ease of emptying the canister or dust collector was given high marks, especially since some models now come with self-cleaning features. Vacuum cleaner owners also appreciated the ease of getting their units serviced and the outcome of the repair work. The timeliness of the repair ranked slightly lower, while the courtesy and helpfulness of the technician were lowest on the list. The ACSI Household Appliance and Electronics Study 2025 was based on 16,205 completed surveys. Customers were chosen at random and contacted via email between July 2024 and June 2025.
