Reviewers often applaud Slendertone devices for strong performance and hard-wearing belts. Delivery experiences vary widely, from fast, well-packed orders to shipments that arrive late, go missing, or get held at customs. Replacement gel pads draw frequent comments about high prices and patchy availability. Opinions on instructions and fit differ from one user to the next.
Examples from available reviews (Sep 2025 – Mar 2026).
Items never arrived and customer service only advised to keep waiting.
“My items never arrived”
The delivery was prompt according to reviewer.
“Prompt delivery”
Replaced an old 20-year belt and is pleased to have a new one.
“Had to replace my 20 year old Slendertone belt”
Gift recipient had no complaints but electrodes were expensive and scarce.
“electriode (patches) were found to be very expensive and then unavailable”
Reviews point to two clear service experiences: fast dispatch with solid packaging, and repeated reports of deliveries that are delayed or never arrive. Several customers say orders were held in customs, or that payment was taken without the goods turning up. A number of low-rated reviews describe cases left unresolved and long waits for refunds or replacements.
Views on value are split between buyers who see the devices as good value and those who focus on the cost of accessories. Replacement gel pads draw specific criticism for being pricey and sometimes out of stock. A few reviewers say the purchase felt like a waste when the sizing or fit was wrong.
Many users describe simple setup and noticeable results from the belts and arm devices. Some highlight ease of use and visible toning after weeks of use. Others say the instructions are unclear or report fit and sizing problems.
Several reviews praise durability, including people replacing decades-old belts and getting similar performance. Other comments mention items arriving defective or incomplete, and pads that turn sticky around the edges. One review called a product unusable because key details were wrong and delivery was late.
Feedback on customer contact is mixed, ranging from friendly, helpful support to emails that go unanswered and no progress updates. Positive experiences include quick replies and issues resolved. Negative accounts often link poor communication with refunds that stall or missing parts that never get sorted.
Ratings show a clear split: high satisfaction with device performance, and low satisfaction with fulfilment and after-sales problem solving. Positive reviews point to quick delivery and devices that work well. Negative reviews focus on lost parcels, silent support, and refunds being refused.
For each review, the core experience based on original source reviews.
