For me, simplicity was key. I chose a model that was straightforward to attach and detach, with clear instructions on how to operate it safely.
Price and Value
I compared prices across various brands and models, balancing cost against features and build quality. Sometimes spending a bit more upfront meant getting a more reliable and longer-lasting product.
