Ive done this too. With both toys and lingure. If its something i know i wouldnt want to buy (or at least be open to the idea of trying) im never going to enjoy the reviewing process.
Whats the point of putting myself through the slog of reviewing a pin pint tappy toy (the shapes i never get on with) or trying lingere i know will never suit my shape.
I always worry when we get really big toys in the normal testers that someone isnt going to check the item page 
clicking the buttons is so easy inevitably someone is just not going to look at the sizes and end up soghnig up for a 6” circumference dildo or a 8” plug or something
