This Chom Chom lint and hair roller does work as advertised IF it is used correctly. We mainly use this Chom Chom to clean up the hair left on the faux leather furniture by our constantly shedding Sable German Shepherd. It does indeed work really well for that purpose. This Chom Chom also picks up little pieces of lint off of the furniture very well. However, this Chom Chom is NOT going to vacuum the entire house by itself, so don't expect miracles from it.This Chom Chom is designed to be used in short back and forth strokes, and not long rolling motions, as the hair collector bar does not turn 360 degrees (it flips back and forth). The hair collector pads are designed to collect hair and lint by building up static electricity through friction, and then the squeegee deposits the hair and lint into the easy to empty storage compartment. If the Chom Chom is used in one long continuous direction/motion it will not work correctly, and I am quite sure that is where the very few negative reviews are coming from.Also, as specifically stated in the included instructions, this Chom Chom is NOT designed to be used directly on humans or pets. It is not a sticky clothing lint roller or a dog/cat brush. The instructions also state that this Chom Chom will not work on hard or smooth services. It needs some friction from rough furniture material in order to build up static electricity on the cleaning pads. As I previously stated, this Chom Chom does work very well IF it used as directed. Just don't use it for unintended purposes, and then leave a bad review because the instructions were ignored or not read at all.While I would have given this Chom Chom 5 stars just because it works so well for its intended purpose, it does have a couple of shortcomings. First off, if a finger is not placed over the door latch of the hair storage compartment while using the Chom Chom, the door constantly flips open and the collected hair goes everywhere (I learned this surprise the hard way). Maybe I received a Chom Chom with weak door latch? Also, this Chom Chom is made of cheap/thin plastic, so it will flex if too much pressure is placed on it during use. Also, the thin plastic construction does bring the long term durability of the Chom Chom into question.In conclusion, I do highly recommend this Chom Chom, as it does work very well for cleaning pet hair as advertised, IF it is used correctly. However, with the weak storage compartment door latch, and the cheap plastic construction, I can only rate the Chom Chom 4 stars. Personally, I only paid $18 for the Chom Chom on Amazon Prime Day, so cost was really not an issue just to try it out. However, it did take over a week to receive the Chom Chom, with 2 day delivery actually being shown in the product listing, so just be prepared in advance that the delivery of the Chom Chom may be delayed due to its immense popularity. However, that is not the fault of Amazon or the Chom Chom itself.UPDATE: This Chom Chom works so well at cleaning up dog hair that we now own 3 of them that we keep and use around the house. The strange part is that even though the name "Chom Chom" is technically a proper noun, we now use it as a verb in our house, as in "I just Chom-Chomed the couch." Good stuff!UPDATE #2: I recently purchased the Black & Decker version of this Chom Chom hair & Lint Removal Tool (I left a comprehensive review for the B&D product as well) for comparison with this Chom Chom. While both this Chom Chom and the B&D versions of this tool work in exactly the same manner, and equally well, the B&D version is a higher quality product, IMHO. The B&D tool has a thicker rubberized purple handle, a translucent purple lint storage compartment lid, and it operates much more quietly, without the occasional loud squealing noise that this Chom Chom makes. The lint compartment door on the B&D tool also stays securely closed until it is actually opened by the user. The best part is that the B&D hair and lint removal tool is about half the regular price as this Chom Chom version (go figure). I gave the B&D tool 5 stars compared to 4 stars for this Chom Chom. I invite people to try both products and see what they think for themselves. I am sure that they will agree with my opinions on both of these very good hair and lint removal tools.
