Well worth the price especially for home usage - I got about 8months out of mine before it kicked the bucket. It was used hard too, sometimes 145 for 2 weeks straight. For the house it's good
I have two at work, one of which is always at 142 doing 48 hr beef roast. The other will usually be doing 145 pork or 165 turkey breast overnight. I try and change them weekly. My kickstarter (4 yrs old?) recently died, others are 3 yr and 1 yr respectively.
90 bucks is a great deal, may have to pick up another. Thanks for posting.
