When purchasing pre-owned gadgets, it is important to consider the following points. Firstly, avoid choosing devices with repaired motherboards or screens, as the lifespan of repaired devices tends to be shorter, and they are prone to malfunctioning soon after purchase. For example, iPads with replaced external screens may experience dust entering the internals, leading to degraded display quality and eventual detachment of the screen with prolonged use. Additionally, it is not recommended to purchase iPads with body deformations or dents, as the bent or dented body can easily damage the iPad's screen. At Digicycle, we only sell iPads with intact screens and bodies.

For Apple Watches, we strongly advise against selecting watches with screens replaced by third-party repairers, as these repaired watches no longer retain their waterproof capabilities. Waterproof functionality is crucial for the everyday use of an Apple Watch.

When it comes to purchasing a MacBook, it is advisable to avoid devices with aftermarket screens or repaired motherboards. If the budget permits, it is recommended to opt for the MacBook series with an Apple M CPU. The introduction of "Apple M" CPUs has been revolutionary, offering superior performance, heat dissipation, and energy efficiency compared to Intel CPUs.
