I had two condensate pumps die on me recently (see my review of the Little Giant), with all the unpleasant consequences: flooding of the basement, etc, so I decided to get this one as a spare.It just arrived, so I unpacked it promptly, but haven’t had the time to install it yet.You can see the photos in comparison to the letter-size bubble-lined plastic bag that Amazon uses to ship stuff.Should anything disappoint, I would update the review.It’s identical in form and functionality to the typical condensate pump. It comes with only one discharge port, which typically doubles a one-way valve.Lengthy Disclosures Follow:I objectively reviewed this merchandise in exchange for a “free” sample. The quotes indicate that it’s not exactly free, as it’s treated as income, and in my tax bracket, I would need to pay a sizeable chunk of it back to Uncle Sam. Nor am I eligible to return some really abysmal or poorly chosen products, as I would normally do, instead I am stuck with them. Be assured of my lack of bias, as I have nothing to gain.I must admit, I gradually learned to distrust Vine reviews myself. When I pick products, I start by reading their reviews, and naturally some early reviews often came from Vine, and these reviews often turned out to be of very poor quality, often directly contradicted by my own experience later.No wonder, I don’t attach much credence to them, even though I am one of those reviewers. Why is that? I can only guess the reasons, but let me share six of them here, as follows:First, Vine reviewers are consumers, not professional testers, and that shows. Many items would require a calibrated testing equipment, or at least anther similar item to compare, in order to get any meaningful verification of their utility. Even a simple thermometer is impossible to review, unless you have another one to compare, and then does the quality of the latter make it a suitable and objective tool for such a measurement?Second. Vine reviewers are rushed to review a sufficient ratio of received products in order to remain current. That introduces constrains. Certain items that e.g. require installation or other time-absorbing activities neither can be quickly assessed, as their qualities would only be verified in a quite involved and time-consuming way. Many aspects, such as e.g. longevity, reliability, battery life, or generally durability are by definition impossible to assess quickly. I recently revisited and updated some of my reviews going back a decade, but few reviewers do that.Besides, the system is far from perfect, and this one is a good example. My original review was somehow wiped out, and I had to partially re-type it and find the photos back to re-insert them, etc.Third, Vine reviewers are more likely to order items that they either don’t need quickly. I must admit I am guilty of ordering spares that I anticipated I would need in the future, e.g. this pump. Therefore, your chance of getting an accurate review from someone whose pump is already installed is much higher.Forth, the “free” receipt means that the lower income tax bracket a reviewer is in, the lower is the penalty for ordering stuff mindlessly. That in turn may mean that neither those reviewers are sufficiently knowledgeable about them, nor have enough brains to assess them appropriately. Naturally, your chance of getting an accurate review from someone who actually needed the item, and researched it carefully before spending their own money earned commensurately with the value of services they provide to their fellow men, is much higher.Fifth, Vine reviewers are consumers, not professional testers, and that shows. Many items would require a calibrated testing equipment, or at least another similar item to compare, in order to get any meaningful verification of their utility. Even a simple thermometer is impossible to review, unless you have another one to compare, and then does the quality of the latter make it a suitable and objective tool for such a measurement?Sixth. Vine reviewers are just people, and they often cannot be trusted. E.g. I just received an item, with dimensions certified by several previous Vine reviewers, same dimensions listed by the advertiser. What’s the risk of getting it wrong? It turned out that they were all false, and the previous reviewers did not bother to measure the item, they just copied the item description.Which way are these Vine ratings skewed, if at all? Very often I see reviewers penalize a product, because either they didn’t read the description, or because they thought a certain word means something else than a dictionary definition. They often admit it openly, which I found hilarious.However, I give the five-star rating to items that I only unpacked, examined, and found matching the listing’s description, but didn’t have time to use yet, and only later I come back to update my review and lower the rating, if I find the product disappointing. This second step is not required for Vine reviewers, and I often see Vine reviewers promised an update in reviews dated months and even years ago, to no avail.
