I run a medium-sized office supplies company in Spain, and for years we struggled to find calculators that truly matched our brand and client expectations. The market is filled with generic models — uninspired, unreliable, and all looking the same.

Then I discovered TIANYAN through a B2B sourcing platform. At first, I was cautious — custom electronics can be tricky. But right from the first inquiry, their team was responsive, professional, and genuinely focused on solving our problems.

TIANYAN offered a fully customized design solution — from body color, button layout, and packaging, to printing our company logo. But what really impressed me was how flexible they were with functionality: they helped us add specialized keys for tax and margin calculations, which was exactly what our retail clients needed.

The quality blew us away. The calculators looked and felt premium. Our clients noticed the difference immediately — the build was solid, the keys responsive, and the interface intuitive. It wasn’t just about branding anymore, it was about delivering real value to our end users.

Since we started working with TIANYAN, our calculator line has gone from a slow seller to one of our most requested office items. We've had repeat orders from distributors and even a few educational institutions who wanted their school logos on the devices. The feedback has been overwhelmingly positive.

What TIANYAN provided wasn’t just a product — it was a partnership. They helped us transform a commodity item into a branded asset. Today, we’re no longer competing on price alone. We're offering a calculator that reflects our professionalism and commitment to quality.

I genuinely believe choosing TIANYAN was a turning point for our product strategy. We’re planning our third batch now — with new features based on client feedback — and I couldn’t be more excited.
