Feedback from distributors, private-label brands and wholesale buyers who source screen protectors from JJT.
★★★★★"We've reordered tempered glass for 6 quarters straight. Defect rate stays under 1% and lead times hold even on 50,000-pc runs. The supplier we used before couldn't keep spec consistency past 20k — JJT hasn't missed once."
★★★★★"They designed our retail card insert and printed our logo from a single reference image. Samples in 4 days, full run in 12 — no back-and-forth, no setup drama. Exactly what a private-label launch needs."
★★★★★"Mixed-model containers arrive correctly sorted and labeled, with SGS and RoHS docs inside the carton every time. Customs clearance has never been held up. Sales team responds same day — even on weekends."
★★★★★"My Amazon FBA store started at 3,000 units. Everything arrived FBA-ready — FNSKU barcoded, poly bagged, suffocation warnings on every bag. Zero units rejected at the fulfillment center across 8 months. Now running 18,000 pcs per order."
★★★★☆"We run 4 phone repair shops in Manchester. One batch had uneven hydrogel cuts on roughly 40 of 500 rolls — not flush on curved edges. Sent photos; JJT shipped a replacement within 6 working days and gave a 10% credit on the next order, no argument. That kind of no-fuss resolution from an overseas factory is rare. Four stars because it happened — their handling earned back the trust."
★★★★☆"I white-label screen protectors on Shopify under my own brand. The first batch had offset logo printing on about 30 of 500 retail sleeves. They reprinted and shipped via DHL at their cost within 8 days. They now send a pre-shipment photo as standard — I didn't even have to ask. One star off for the initial miss, but the follow-through was genuinely impressive."
★★★★★"We supply mobile accessories to 60+ independent phone shops and repair counters across Texas. JJT handles mixed-model orders — sometimes 25 SKUs per shipment — everything sorted by model with numbers on the inner boxes. RoHS docs always inside the carton. Our retailers have never complained about the packaging; that's saying something."
★★★★★"We trialed JJT tempered glass across our 12 electronics stores in Warsaw and Kraków. First-quarter defect rate: under 0.5%. The anti-glare matte variant outperformed our previous supplier in customer feedback. CE and SGS documents arrived two weeks before the goods — our compliance officer was impressed. Reordered at double volume for Q3."
