Most exercise and diet books focus on the endomorph who can easily gain size, and this can lead ectomorphs astray due to the complex eating and exercise patterns required. Scrawny to Brawny is straightforward and is easy to follow, allowing one to gain size appropriate to one's body type. Is this product review negative?

input:  Now, answer this question: Title: Don't Lose Your Keys Review: This is a solid lock that will fit Class II, Class III and Class IV hitch receivers. Mine came with two hardened-steel chrome plated pins (not a sleeve as was illustrated when I bought it). The smaller pin works with Class II and Class III hitch receivers. The larger pin works with Class IV. I use this lock to secure my bike rack and it's tough enough that I wouldn't want to lose my keys. The keyhole is protected by a weather-resistant rubber cover, yet rotates for easy accessibility. This is a rugged, versatile hitch lock offered at a good price. Is this product review negative?
