【工具紹介】ラチェットアダプターが面白い④ KTC BRA21　3/8” トータルバランス№１俺的な評価基準について

Interesting ratchet adapter ④ KTC BRA21 3/8” Total balance No. 1 About my evaluation criteria #工具 #tools #KTC #RatchetAdapter The balance between price and quality This is the ratchet adapter that I think is the best. Although the internal structure is different Appearance snap-on type Good place Easy to speed up Good gear accuracy etc There is nothing that stands out like this. No major complaints sunday mechanic If you only use it occasionally A lifetime of peace of mind Even for many general users Even for many professionals I think it's the best ratchet adapter for the price. Not so good points Difficult to switch It can be mistaken for a snap-on (lol) Rather than this ratchet adapter Regarding KTC in general Poor customer service... About my evaluation criteria for tools When evaluating tools We evaluate based on these criteria 6 elements ①Price...(actual price/easiness of acquisition) ②Durability・(Recommended torque・susceptibility to rust) ③Accuracy...(Actual measurement value, tolerance, play, bending, backlash) ④Performance...(versatility, number of gears, weight, size) ⑤ Usage feeling (Idle torque, balance, grip shape) ⑥ Satisfaction (appearance, texture, history, status) (The explanation in parentheses is part of the evaluation guide) With the balance of 6 elements Product features and classes Manufacturer's thinking It becomes a guideline to aim for With the required amount of 6 elements The compatibility between the tool and the user I can understand it somehow Tools that cannot be used and tools that cannot be used As a guide for selecting tools Ratings are organized on a 5-point scale. Elements ① to ③ are Products that do not meet the user's requested value Often becomes an “unusable tool” Elements ④ to ⑥ are Products that do not meet the user's requested value It tends to become an “unused tool” Tools with low ① (high price) and high ⑥ are Easy to become a “coveted tool” If ②③ is high, it is a “reliable partner” ④ If ⑤ is high, it becomes a “tool that is often used” If ⑤⑥ is high, it will become a ``tool that you will be attached to.'' ① to ⑥ are often correlated. If you try to increase the number of gears in ④ The strength of ② decreases. If you try to increase ④ while maintaining ②, There is a tendency for ① to decrease. Professionals tend to emphasize ② and ③. General users When choosing the first tool etc. ① and catalog data-like ④ I think there is a tendency to emphasize Evaluation criteria Evaluation criteria are categorized by type. It is an approximate relative value. Rating 3, is Based on the average value of domestic manufacturer products Rating 1, is For the average user I'm thinking about the OK line as a guide. (Unusable levels are rated 0.) Among 1/4 products Even with extremely strong products with a strength rating of 5. The strength is lower than the product with a strength rating of 3 for 1/2 It's like that Regarding strength, please refer to the manufacturer's catalog data and short term strength test What I learned from professionals and general users Condition of wear and tear on used items, etc. This is an evaluation within the scope of research. We will continue to update as new information becomes available. The importance of each number is It varies depending on the person, so Sensitive numbers such as the overall score I don't think it makes much sense It is not a “grade sheet” to judge superiority or inferiority. This is a "performance table" to understand individual characteristics. This is a personal review for organizing purposes. I would be happy if this was helpful to you all. I roughly evaluate it like this. (If there is demand, I am thinking of making a video that explains it in more detail) The evaluation of KTC BRA21 is ① Price...2 ¥6,049 ②Durability・4 ③Accuracy...3 ④Performance...4 60 gears ⑤Usage impression・3 ⑥ Satisfaction・3 When in doubt, this is a KTC-like product that lives up to the KTC name. Whether you are a professional or a general user A product that is dissatisfying because there is no dissatisfaction This is a product that will not disappoint first-time users. Not betraying user expectations and trust As a manufacturer and a brand may be the most important thing Regarding the price I don't think it's expensive considering you'll be using it for a lifetime. If you are thinking about moving to Nepros in the future There is a slight price difference for comparison TONE RAD30 ①Price...5 Tone is a little cheap You can also buy it at home centers. Highly rated for ease of acquisition ②Durability・3 ③Accuracy...2 Larger play and larger wobbly feeling ④Performance...5 72 gears ⑤Usage impression・4 In terms of ease of idling, it's definitely a 5. However, the harsh feeling is negative. ⑥ Satisfaction・3 Ko-ken3755 ①Price...3 ②Durability・4 ③Accuracy...4 ④Performance...3 45 gears ⑤Usage impression・4 ⑥ Satisfaction・3 Ko-ken2755 ①Price...2 ②Durability・4 ③Accuracy...4 ④Performance...3 44 gears ⑤Usage impression・4 ⑥ Satisfaction・3
