I love cooking with silicone spatulas. I never seem to have enough on hand. These were great. They held up heat-wise. They performed well in rigidity (large steel core, but nowhere near the point of making the tools heavy and unwieldy). The larger spatula had much less flex than cheaper competitors (See pictures. This set is gray The competitor is red. I could flex this 100 degrees versus about 180 in the competitor).
While you need some flex, 180 degrees is too much, That being said they cost more. This set is really good. Worth its price. If you have $5-7 extra to spend get this 3 piece premium sets. If you pick the cheaper set you'll live, but don't ever try these because you'll regret what you're missing.
